You know what can top a homemade, out-of-focus video of Ice Cream Sandwich running on Asus' old Eee Pad Transformer? An official video of ICS running on Asus' new Eee Pad Transformer Prime.  Nvidia has just released a polished (yet insanely short) video of the new quad-core Tegra 3 tablet running Android 4.0. While the tablet won't launch with the OS in early December — shipping units will boot up Android 3.2 — Asus has promised an ICS helping before the end of the year. And it looks like it's going to be well worth that short wait. Of course, the demo is very staged and only a few things are shown, including a five second look at a game called Riptide which uses all four cores, but from what we can see everything runs insanely smooth. On top of that, some of the new ICS features — creating folders, etc. — look quite useful on the big screen. We could go on and on about this, but we will let you get to the video below while we try and track one of these down to do a proper video hands-on.
