Wonder if Office on RT will lag with the S800 (or Tegra4) like it did horribly with Tegra3.
IF they had chose the T3+ @1.7ghz it wouldn't have been an issue. So no, with either of the new ones no problem. They are much faster. A 1.3ghz A9 and crap gpu, compared to quad A15 at 1.9ghz or S800 at 2.2-2.3ghz both with great gpus. There is a HUGE difference between them.
Then again, it doesn't come out and say WHICH qcom chip it has. Might be an S400, which would make it useless for gaming, but I think the modem version is aimed at business people anyway. T4 will be for the users seeking FUN and not aimed at business. They supposedly have outlook coming though so maybe they'll both sell to business. I don't know any business users that don't have a phone on them already, so I think even the wireless aimed at business is kind of useless for a large portion of them. You don't get much work on these besides some emails and browsing. Nobody creates anything on tablets or phones.
