Hands On: Is Acer’s Iconia Tab A510 Fit for Olympic Competition?

If you’re an Android device manufacturer in today’s crowded tablet space, you have bigger problems than worrying about how you’re going to compete with Apple. Before even addressing the iPad challenge, you have to kick, claw and bully your way through a field of tablet competitors also running Google’s mobile OS.
Samsung, Asus and Motorola: They’re all doing their best to sweep up that small universe of tablet-curious consumers who haven’t joined Team iPad. And now Acer is making another bid for relevancy in the 10.1-inch Android tablet space.
Does the new $450 slate make a compelling argument? No, it doesn’t. That’s our initial takeaway after about four hours of hands-on use.
As soon as I took the A510 out of its box, I noticed the back of the tablet is adorned with the familiar five-ringed logo of the Olympic games. It’s a fine logo. It always has been. But a simple branding tie-in isn’t a relevant “feature.” The A510′s physical design is much more germane.
The A510 measures 0.42 inches thick and weighs 1.54 pounds — heavier than the Samsung Galaxy Tab 10.1, Asus Tranformer Prime and new iPad, but not by much. There’s a soft, rubberized coating across the back of the tablet. It has an appealing softness to it, and also adds a bit of grippiness — welcome considering the tablet feels a bit hefty.
Indeed, this tablet is likely to get heavy after a couple hours of continued use if you had to hold it up yourself.
Unfortunately, the large screen didn’t impress me, despite its 1280×800 resolution. It’s an IPS display that offers solid off-axis viewing, but in this age of Super AMOLED screens and Retina displays, it’s not a stunner by any means. And all visual content — the home screen, apps, websites and photos snapped on the 5-megapixel rear camera — renders on the cool side of the color spectrum.
While I’m annoyed by competing screens that err toward over-saturation, the A510′s display is too pale for my tastes. And while, technically, the A510 has a high-definition screen (insomuch as it supports 720p), app icons look blurry upon close inspection. Text rendered on websites and throughout the OS looks sharp, but the screen doesn’t come close to wowing me.
THe A510 boasts 32GB of storage, a quad-core Nvidia Tegra 3 processor, and 1GB of RAM, which helps the tablet run quickly, at least on the lock screen. However, drilling down into features found in the OS itself — an Acer-skinned version of Android 4, a.k.a. Ice Cream Sandwich — presents a different sory.
Acer’s most obvious addition to ICS — and its biggest attempt at competitive differentiation — is the increasingly familiar “Acer Ring,” a user interface element that pins frequently used apps and content items on a touch-sensitive carousel.
Unlocking the tablet requires a swipe of a lockscreen ring. Swipe to the right, and you’re in, picking up wherever you last left off, whether on the home screen or in an app. You can also swipe to the left to go straight to your web browser, photo gallery, Google search or the camera app.
Once inside, you’ll find a pale green ring icon at the bottom of the home screen — tap it to bring up yet another ring. This new ring features a volume slider, a fan array of icons for bookmarked webpages, and quick-launch controls for the photo gallery app, the web browser, OS settings, and a screenshot tool.
The ring on the lockscreen reacts quickly. The ring summoned from the menu bar — not so much. Its rolling animation launches slowly. Launching into apps and moving the fan of bookmarked webpages is quicker, but Acer’s whole ring experience feels like a forced exercise in product differentiation.
Ice Cream Sandwich is Google’s breakthrough OS, and there’s really no need to re-skin it unless a manufacturer can add real value and innovation. But the Acer Ring doesn’t deliver this. Instead it just offers an second way to access elements that can already be exposed on a smartly configured home screen.
While the A510 offers competitive internal specs, its display isn’t anything special, and its Ring U.I. is more of an innocuous curiosity than a useful feature. And the Olympic rings logo, while full of history and import, is nothing more than window dressing.
Again, we only spent a few hours with the A510, but nothing about the experience told us this tablet is the 10.1-inch Android device to beat.

    HTC One X shows HTC ditched battery life, chose thin instead

    Which would you prefer: a phone so gossamer-thin it practically disappears when you slip it in your pocket, or a phone with more stamina than Charlie Sheen double-dropping viagra? HTC reckons you want thin rather than long-lasting.
    The company behind the popular HTC One X, HTC One V and HTC One S reckons a slimline casing is more of a priority for phone fans than a lengthy battery life. One of HTC's chief strategy wonks said that after asking customers, the company ditched battery-boosting plans to concentrate on thinner phones instead.
    There's something insanely seductive about a thin gadget -- ultrabooks and OLED TVs make our heads reel as giddy as a schoolgirl. But let's face it: how much thinner can phones get? They need to have some weight in our hands and in our pockets.
    And lest we forget, the extremely thin HTC One X had a minor problem with flexing.
    I reckon HTC is misjudging what customers want. Here at CNET, we've noticed a growing discontentment among our readers with phone battery life. Many of you lament that your phone barely lasts a day of solid use, and with dual-core and quad-core powerhouses hitting shop shelves, phones are only getting more energy-suckingly powerful.
    More powerful phones don't necessarily mean worse battery life, as it's all about the software and hardware working together in the most efficient way. That means only using power when it's needed, and wringing the last drops of juice from a battery.

    Which would you prefer: a svelte smart phone or boffo battery life -- or somewhere in between? Tell me your thoughts in the comments or on our Facebook page.

    Free, Ad-Supported Mobile Apps Are Killing Your Battery

    Filed under "you get what you pay for": Researchers at Microsoft tested the energy consumption of various apps on Android and Windows Phone (iOS restrictions kept them from testing the iPhone) and found that up to 75% of an app's energy use goes to power the advertisements in free, ad-supported apps. The numbers may not have much of an impact without tying them to an app you actually use, so what about an extremely popular game like Angry Birds:
    In the case of Angry Birds, research suggested that only 20% of the total energy consumption was used to actually play the game itself.
    Of the rest, 45% is used finding out your location with which it can serve targeted advertising.
    The lesson: Next time you're choosing the ad-supported version of an app over, say, its $1 counterpart, you may want to consider whether you're willing to pay extra just to keep your ACER Aspire 5715Z battery going longer. Yet another way free stuff isn't always worth it.

    It would need to much in privileges. Jail breaking allows installation from other places, and tweaks, etc. but ad-block requires re-routing the traffic for certain sites, interfering with the DNS lookup. Way out of Jail-breaking's league. But possible on a rooted Android.
    Just mod the hosts file.
    Congratulations! Another person spreading misinformation out of ignorance!
    I don't know what you're on about as far as privileges, jailbreaking's biggest negative is security because applications installed through Cydia and other sources can do as they'd please. Change your bootloader and install Android as a dual boot, or block ads, either way the jailbreak allows it.
    As per the original issue:
    AdBlocker - Blocks ads in Safari and other applications, does a pretty good job of it but misses some ad sources. For example IM+ and Pandora
    Firewall iP - Allows one to block connections to individual hostnames and IP addresses and apps, with easy options for length. (Once, session, always, etc...) I use it to block the ads in IM+ without issue, as well as a few other applications.
    Pandora Skip Hack - While it allows overruling the skip limits, its best feature is the fact that it blocks the text and audio ads while listening.

    thanks for the refs. I tried AdBlocker, but felt like it was really gumming up the works and slowing things down (when the opposite is the goal!). Firewall IP sounds ok, except, which hostnames/IPs do you block?
    BTW, is your name a killing word?
    Edited by luckycharms at 03/19/12 2:29 PM
    and block which IPs? Found this, not sure if it's reliable: [modmyi.com]
    Edited by luckycharms at 03/19/12 2:32 PM
    update: modded with the file linked in the link above. seems to work like a charm! thanks for the tip, CamJN!
    I'd trust a hosts file tutorial from modmyi. Worst case scenario it MIGHT block something legitimate, but that's a pretty small possibility. The steps are correct for getting it there, so you're fine on that route.
    There are two Cydia packages for AdBlock. AdBlock which I had some problems with, and AdBlocker which I've enjoyed using thus far, and haven't had any issues with. Ensure you're using the right one.
    Firewall iP brings up a prompt every time a network connection is attempted. It's then a matter of blocking the ones that look like ad sites and allowing the ones that look legitimate. Generally if an application contacts the developer's domain, I allow it, and if it says ads I'll block it. I'll also block any plain IP addresses. Once you've done this, make sure the application works if it does anything online. If it doesn't, go to Firewall iP's settings and remove denials until it works for you. It's a lot of upfront effort every time you install a new application, but it works well and I think it's worth the effort.
    Good luck!
    Oh, and no. It's my two favorite characters from fiction. I'd link to descriptions of them but all the encyclopedic entries I find are poorly done and look like gibberish if you aren't familiar with them already.

    Not to get all preachy, but by going through all the effort to block ads, you're denying the developer a paycheck for all the hard work and time they put into making an app and offering to you FOR FREE. Just buy the app and quit whining about the $1. Seriously!
    promoted by CamJN
    Meh if a dev doesn't want their app stolen/ads disabled it's not hard to detect a jailbreak and refuse to start the app. I've done it before.
    @David Nurbin
    Uhm... Jailbreaking is a root of the device, with access to everything, including all system files. Not to hard to reroute traffic. That's like saying an administrator of a PC cannot modify the hosts file.
    @TechDaddyK Eh, I just leave the app running all night while I'm syncing to my computer (Hooray for Synchrocity) then kill all ads while working with my iOS device in the day. They get their paycheck (much more that they normally would too) and I still keep my Dell XPS M1730 Laptop Battery life intact.

    In-App Ads Are Destroying Your Battery Life

    You intuitively know that all of those applications running in the background on your phone are latently eating away at your battery's charge, but a new study reveals that the main culprit isn't any useful function. It's location-pinging ads.
    The study, conducted by a team lead by Abhinav Pathak from Purdue University, analyzed the energy used by several popular free Android apps (PDF) like Angry Birds, Facebook, the New York Times, and Chess. The team developed an "energy profiler" they call "Eprof" that determines what processes within an app are using energy. The results are shocking: 65 to 75 percent of energy consumed by the free apps studied are used by third-party advertising modules within the programs. These apps continue to run in the background even when you're not actually using the app. Only 10 to 30 percent of that energy is used to power the applications' "core functions."
    Apps shouldn't continue to serve you ads when you're not locking at the apps. It's a bug, or something more nefarious. According to the researchers, developers don't notice energy consumption problems—bugs or otherwise—because most apps are "energy oblivious," meaning that the developers don't pay attention to how much energy apps use.

    From what I've read, ad blockers just block the apps from being viewed. It doesn't keep the app from running and trying to show them. What you're describing implies the ad blocker actually tells the other app what to do. I highly doubt that is what's happening.
    That may be true, I don't detect any significant increase in COMPAQ Presario C307NR battery life. At any rate, it's great because I hate ads.
    An app like AdAway blocks Apps from downloading at all by using host files. The effect is when I was using Ad Free it blocked my emails from Newegg which is why I switched to AdAway. Some ads still aren't blocked though. In this case though while your data might be saved since it won't download the images and such, the pinging for location will still continue causing not much of a HP ProBook 4710s Laptop Battery  saving.
    Yeah depending on the apps behavior when encountering a failure to download ad content you could be killing your battery even more. I'm guessing diminished display activity including flash style ads more than makes up for a bunch of retries since display usage is a big SONY VGP-BPS13/S Laptop Battery waster.
    The better thing to use is a firewall to block that data all together. (most) Games don't need data.

    Rooted phone allow you to install powerful firewall which actually controls internet access *per application*. Say, I can set Wikipedia for full access (Wifi or 4G) but Angry Bird to no-access. This will at least eliminate unnecessary data usage and some of the power drains associated with it (on the cell radio side). Although to be fair it will not stop the app from waking the phone up and consuming CPU cycle...
