Definitely the smoothest experience I've had on this tab; having tried Stock, Overcome and ICS Alpha 2.
Camera and Video playback (Youtube, YouTubeHD, Netflix I'm assuming) are of course a no-no still at the moment.
SD Card Video playback has been no problem for me, save for a bit of stuttering on high profile MKV's, but that's the same on every rom.
Streaming Icefilms worked flawlessly, which leaves me happy.
All I want, a fix for the strange half a second Rotation stretching, HD video playback fixed, and ma camera! This would be the perfect rom.
The currently running widgets thing has the app photos rotated 90 degrees, and the screen streches for half a second when rotating.
Otherwise, I'm very happy to see that my tablet is capable of attaining speeds like. Absolutely flawless; what I would give to have a complete ICS rom. xD
