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.

    Naw, Windows 8 still isn't interesting to me. Even oddball projects like Plasma Active are more interesting.

    Except I HAVE actually used Windows 8, I do not agree, and its still inappropriate.

    I agree it's inappropriate. Calling your readers ignorant is not a way to build trust and I have to say honestly that comment damaged Anandtech's reputation.

    I'm using Win8 on my home rig and there are things I like about it (some nice performance enhancements) but metro is NOT one of them. Combining touch interface into the desktop was a natural evolution, but what MS did by trying to make one interface work for phones and desktops is going to be a big mistake IMO. Windows 8 is going to be much more hated than the Office Ribbon ever was. The hot corners, full windows start panel and re-emergence of the active desktop it provides are all going to be disastrous IMO.

    Regardless of how you feel about Windows8 calling people Ignorant for disliking the UI isn't professional and I normally come to this site for professional well thought out reviews EVEN if I don't agree with the conclusions.

    If you treat Modern UI like a fancy start menu, everything is fine. If you obsess about Modern UI and spend long hours glaring at it and muttering curses, then I can see where you might have a problem.

    Anyway if you're really hardcore into murdering the new start menu, there are options for that too. But you were obviously ignorant of this. Ooops! Was that inappropriate? Want some Pamprin? Ah damn there I go again being inappropriate. Probably not politically correct either.

    It's the Metro/Modern user interface, being discussed in the context of using it with a mouse. I don't understand how it doesn't apply, considering this particular tablet is shipped with a keyboard/touchpad attachment.

    I happen to agree with your opinion in this article Vivek, but augiem has a point - using the "ignorant" comment in your article is pretty unprofessional (i.e. harsh) for someone writing an article/review :-( What about addressing it in a different, less harsh way?
  • VivekGowri - Tuesday, October 23, 2012 - link

    Yeah, I agree that it sounded a bit harsh in my head too but I was more focused on getting the article out in time rather than worry about that one word. Does "uninformed" sound better?

    What about the fact that it fills the screen? What if you don't want to lose visibility of windows you have open? That's gotta count for something, no?

    I myself use other launchers, so I shouldn't be affected =P.

    Ignorant *does* mean uninformed, the word 'ignorant' has just gotten twisted by popular culture to be equivalent to 'stupid', which it is not.

    How about, has a different opinion from. Honestly, the level of superiority on these tech boards is unbelievable.
