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.

    Nah, I totally agree with Vivek's statement and I don't believe it's in any way inappropriate.

    I don't know what phrase of astonishment to use. He clearly said a Win 8 review is coming. Part of the experience is transitioning between the two modes, which is more specific to this laptablet (my hybrid term for the hybrid machines) and as such should be covered in this review specifically. Windows 8 reviews will come in Windows 8 reviews.

    Might not be appropriate, but I strongly agree with his assertion. I'm using windows 8 on various machines and it's not a big deal at all. Truthfully I still prefer the start button because it was less jarring, but the actual start menu was a piece of garbage. I NEVER went into the tree mess to find something, I'd just type and search, and that works the same in windows 8 (almost), except you have to hit windows-w to search settings.

    I agreed with this quote and was happy to see Vivek say it. I don't know why there's no option to start on the desktop when booting your PC, but tbh, it takes one click to get there and then you're back on your normal 'workflow' (unless you accidentally manage to open a Metro App and can't find your way out). Is one click a day worth all the complaining?

    right on Vivek! pwn those oldfags, reclaimers,etc

    that's EXACTLY my impression of Metro, glad smart reviewers like Vivek at last stated the truth here

    hehe I'll keep enjoiyng reclaimer's deep sucking of crapdroid cock. don't forget to swallow reclaimer :P RT is pwning ya oldfaggy ass as of RIGHT NOW LOL :)))

    Vivek you're wrong, during recent Q&A with Surface team they clearly stated that they are being run as a profitable business from the start and hence no subsidies on the hardware, nothing at all. Hence the high Surface price of $499 and up. You should read that Q&A before spreading false rumors, thank you :)

    Edited to reflect this - overall point is still valid though, they're probably taking back less profit than everyone else by design. And of course, no software licensing fees.

    Why would they make the tradeoff AMD has to make when they had the S4 as an option? Or better yet, the S4 Pro? The timing was perfect! Optimus G released with it, why couldn't the VivoTab?

    Great review! One quick addition would make it better: Can you list the combined weight of the tablet with the laptop dock in your opening table? It would be great to quickly compare this to other form factors (i.e. laptops, netbooks, etc.)

    You mentioned that the processor load is kind of high for typing in office for example, or loading programs - how "smooth" is the feeling of the UI? I think you said at one point that Tegra three might have seemed laggy at one point but later it was "anything under Tegra 3 would be slow" so does it seem like Tegra 3 is sufficient to power the tablet/prevent any "annoying" slowdowns?
