This is where I think the VivoTab RT really distinguishes itself. If you were to ask me for one reason to buy the ASUS over Surface, this is it. The tablet is quoted as having similar battery life to Surface actually, even though it has a smaller 25Wh battery (Surface RT has a capacity of 31.5Wh, but both manufacturers claim 9 hours of battery runtime.) The higher power efficiency claim is likely due to the smaller display. I saw just under 8.5 hours in our web-browsing test, and a hair over 10 hours in our HD video playback test. These were a bit lower than what we’ve seen from the 2012 iPad, Transformer Prime, and other recently tested devices, but dead on with the Transformer Infinity and not too far off the pace set by the others.

Web Browsing Battery Life

Video Playback - H.264 720p High Profile (4Mbps)

And anyways, when you toss in the integrated 22Wh battery in the docking station, you’re looking at nearly 14 hours of battery runtime in light-load workflows. It’s awesome. Truly all-day computing, something that Surface and the iPad come close to but can’t really match.

    Either way just wait for S4 Pro tablets.

    It's got minor lag in desktop mode, noticeable but livable. Anything slower than T3 though, and livable quickly becomes intolerable. Most of the time, you live in Metro anyways so it's not that big of a deal.

    Just a heads-up, in case it is the Anandtech ad servers, and not my own system: Clicking between pages on this site, I got a popup that looks like adware. The link, after making it non-clickable was this: surveyorster dot net /d/j4u2i16147?r=http%3A%2F%2Fgjetefa.info%2Fin.php%3Fq%3DM%2FOEglLmwNcgOzwtBLg9uSk36%2BpwOyaQwIB9U0Q%3D

    I also saw an annoying "floating advertisement window" recently on the site, which I've never seen in the past.

    I have not seen anything strange while browsing other websites.

    In a google search, I'm seeing a few mentions of similar behavior involving the domain name "gjetefa.info" for other sites (wowhead, etc). I haven't personally seen any redirects like you mention on Anand. If it was my pc, I'd suspect malware and check it out with something like MalwareBytes.

    It has happened to me only twice. I don't remember the URL, but I have clicked on an article link from the main page, got the article, and one second later was presented with a page that copied the facebook design and called itself some kind of survey. I saw fields asking for my name and phone number and something else, but my CTRL+F4 reflexes kicked in. The next time I clicked on the article, that didn't happen. I got one roughly 2 weeks ago and another last Friday, and that's all. I think it's something that wedged itself into the ad rotation.

    No offence to Vivek. But apple comes out with a "new" product, we get a 200 page in depth review with deep analysis from Anand.

    Microsoft releases both a huge new OS, a new tablet platform. and gets Vivek? And like 5 pages of coverage.

    Unbiased? Just based on volume you can tell Anands bias.

    You speak too soon, my friend. Between myself and Anand, we're dumping roughly 20k words of Windows RT-related coverage on you today. Just wait for the full Windows RT review.

    Vivek, This is a slight change of subject.....but do you guys have any plans to review the RAZRi?

    Also, Thanks for this article......are you going to do a similiar one for the Vivo Tab? I'm torn between the VivoTab and the full blown Transformer book. I need AT to help me choose!! :-)

    If you were actually familiar with the site or Apple products you would now they often take weeks longer than anyone else to write a review.
    Don't you need to run the malware scanner on your Android phone now?

    That is just silly, I personally have never gotten a malware nor have I ever met anybody who received one. If you stay away from cracked apps and add ridden games it should never be a problem. Besides I would gladly endure such a nuisance just to have a system that includes a filemanager, able to play almost every media codec, Java, Flash, SD Card slot, complete rom/system/data backup, ability to side load apps, true multitasking, multi-view, SAMBA/FTP/SSH support within the filemanager, DLNA, printer support, removable battery, NFC, ect. iOS is an overrated mobile OS but I'm glad your happy with it, that's all that matters.
