I downloaded and installed this last night on my touchpad, which was previously running cm9alpha2.
The only real problem that affected me with this version is that ES file explorer can't play (or perhaps it's mx player) any files off a windows share. I can connect to the share, copy files to and from the share, check properties, delete, rename, so it's not a permissions/access problem.
But as soon as I try to play it, the screen turns black, and is unresponsive except to hit the back key.
Copying the file to the local sdcard and playing it works fine.
However, this "remote play" worked fine on cm9 with mxplayer.
Other than that, everything I tried, which isn't much, since I basically use it as an alarm clock and media player, seemed to be OK. no mic, no camera doesn't make any diff to me.
