And unfortunately, in more ways than one, which I'll go into more detail shortly. I should note that I'll be comparing this to my ASUS Transformer Prime TF201 Tablet that I've been using for about 3 weeks now; although I will be focusing on the A510. The TF201 is a great device, but it's not exactly perfect. And I'm always looking for something better! So I was hoping to give the Acer Iconia Tab A510 a try, now that there is finally another Tegra 3 device to play with.
I'll also be adding some pictures to go along with this review.
OS & Performance:
Compared to the TF201, there is really no difference in speed or performance. Both are very quick devices and have excellent graphic performance. They have the same version of ICS (4.0.3) and neither have any drastic customizations. Acer does have their short-cut app that gives you quick access to certain features such as bookmarks, camera, and volume. It looks neat, but nothing too crazy here.
I performed Quantum and Antutu benchmarks and found them to be nearly identical, with the A510 getting a slight edge in Antutu (about 11k vs 10.6k) and virtually no difference with Quantum. This of course isn't noticeable in real-world use, but worth noting for those interested. Browsing, playing games, checking e-mail, all work as expected. The built-in browser could be better. But if you don't like it, there are plenty of other options (ie. Chrome, Dolphin, Opera, etc).
Display:
When I first played with the A510, the only issue I had was with the "grid effect." I've heard other folks mention this with previous Acer tablets, but never owned one myself. So what is the "grid effect?" Imagine looking through a screen door or very close to an old tube television, except to a much lesser extent. It's something that's always present with this device and you can easily see it if you look close enough (ie. 6" or so); especially on a lighter colored image.
Unfortunately, these things tend to be quite noticeable to me, and I can even see it when using it at a "normal" usage distance. I can see it on the red Netflix icon, while surfing the web, looking at the sky background of a random picture I have, etc. You get the idea. Although do keep in mind this is very minor and most folks may not notice and/or care. But regardless, it's there.
Grid's aside, the screen does look pretty darn good. It has a very cool color tint compared to the TF201, which is much warmer. In fact, it's really a night/day difference. After watching hours of videos and looking at countless pictures with these two devices side-by-side, I actually kind of prefer the tone on the A510. The white's just look whiter, which is nice.
For a better idea of what I'm talking about, just hop into your TV's picture settings and change the color tint. For a cooler tone, think almost bluish. And for a warmer tone, a bit redder tint. Given a choice, I'd really prefer something more neutral between the two. Of course it's a tablet, not a professional monitor, and a lot of this is personal preference.
However, at the end of the day, it's hard to compete with the IPS+ display of the TF201. Even in normal IPS mode (not IPS+ Daylight mode), it's quite obvious the image is crisper and more detailed. If you didn't have this to compare it to, I'm almost positive you'd never notice and be perfectly happy with the A510's LCD. But I think it's worth throwing out there.
Wireless:
Wireless performance is excellent. Next to the TF201, the A510 normally had an extra bar or a faster connection speed as noted in the Wi-Fi settings of the tablet. Bluetooth works just as it should, pairing up to my BT headphones without an issue.
GPS is also excellent. I didn't even have to go outside and I already had 12 satellites detected as noted by the GPS Test application. Which I'm afraid the TF201 can't say the same, as is currently has 0. Yes, zero. If I go outside, the TF201 might pick up 3-4, but good luck getting a lock. This is a horse that's been beaten to death on other forums, and there is a work-around (not a fix) for the TF201 that adds an external dongle.
So I won't spend much more time on that topic. But if you like to use GPS, it's something to keep in mind.
Speakers:
There isn't a lot to say about the speakers, but they sound so darn good I felt they deserved their own section. :) There are 2 speakers located at the bottom of the device and they sound fantastic (for a tablet). Compared to the single speaker located on the right/back of the TF201, the A510 blows it away. There are also some Dolby specific settings which adds some EQ and sound profiles to play with and make them sound even better.
The only concern is how this will work with certain cases that let you use the tablet in "stand" mode, as they would be blocked. Hopefully case designers take this into consideration, because it would be a shame to block such nice sounding speakers.
Too bad they couldn't put them front facing as they are on the Blackberry Playbook, which also has great speakers.
Hardware:
The physical build quality is excellent. It has a very solid feel and all the buttons and inputs you'd want. You have your standard front/rear cameras where they normally are. Volume rocker is at the top along with a rotation hold switch. Power is at the left directly above the headphone jack. To the right is the MicroHDMI port. Below this on the right is a flimsy flap covering the MicroSD port and what looks like a dead/blank spot for a SIM card (maybe on a future model). I can already see this flap falling off and/or breaking in the future. Stereo speakers are located on the bottom.
Also on the bottom is the MicroUSB port which also doubles as a proprietary power charger for the device. There is also an included MicroUSB -> USB adapter that lets you connect normal USB devices such as keyboards, mice, game controllers, or even a good `ol USB Flash Drive. Unfortunately due to the higher power requirements of tablets, you can't charge it with your PC USB port or your average MicroUSB power adapters that come with smart phones.
As expected from the spec sheet, the A510 itself is noticeably thicker and heavier than the TF201. But it's not enough to deter you from buying it. In fact, because of its soft-touch backing and added thickness, I found it nicer to hold for extended periods of time. At least until you notice that the right-side of the device is becoming unusually warm.
Problems:
This brings us to both the title and the reason why this device only gets a 2-star review; in particular after so many relatively positive comments for the previous 2 pages. I noticed after only a few minutes or surfing the web, that the right-side of the device was becoming uncomfortably warm. I had to set it down as my hand was starting to sweat. I then picked up my TF201 and used it for a while, thinking maybe I never noticed. Nope, it's nice and cool.
So thinking it was defective, I exchanged it through Amazon and got a brand new replacement the next day. Same issue. Except this new one also has touch-screen input issues. Similar to what another reviewer posted a video for, but to a lesser extent. Basically the screen just randomly ignores input or registers an input that's off by an inch or so. Yep, it's just as annoying as it sounds. But at least I know that would be fixed with an exchange.
I measured the back of both A510's with an infrared thermometer and have seen temps as high as 106 degrees (see pictures). Ran benchmarks and performed identical tasks on all 3 devices, and they were all the same. The A510 consistently ran over 100 degrees on the right side and the TF201 never got past 85, anywhere. Unfortunately, that's a deal breaker for me.
So let's wrap this up with some Pro's and Con's.
Pros:
+ Nice screen with "cool" tint and better white balance.
+ Excellent Dolby stereo speakers
+ Super Fast (hey, it's a Tegra 3)
+ Micro USB Port (and full size USB adapter)
+ Solid feel and build quality
+ Plenty of easy to use buttons, ergonomic
+ Wi-Fi and even GPS work extremely well.
+ You can actually get one NOW if you want it. :)
Cons:
- LCD not quite as crisp or bright as the TF201's IPS+ Display
- Faint "grid" effect noticeable on certain images (minor, up close, but it's there)
- Quite noticeably heavier and much thicker than the TF201.
- No Flash for Camera
- Way too hot.
Conclusion:
Overall, I think if it weren't for the "grid effect," and more importantly, the heat issue, this could easily be a 5 star device and wouldn't be hard to replace the TF201 for me. The A510 is still $50 cheaper, feels nicer to hold, has internal GPS that works, better Wi-Fi, and yes, I love those speakers. Heck, if it were down to $400, it would be a no brainer. And this could all change when a cheaper Tegra 3's hit the market in the next few months.
Could I have gotten two defective devices in a row that have the exact same heat issue? Would a case help minimize the heat issue? Could a software update cool things down? Anything is possible, but I'm not going for a third.
