Yesterday, we saw the first glimpse of Sense 4 on Android 4.0 on the HTC Ville. While watching the video, I assumed that the handset was running Gingerbread since it looked just like previous versions of Sense (save for the updated launcher). The only thing that even slightly resembled ICS is the Roboto font in the clock.
Then it showed the version information, which made me feel physically ill. This is Sense 4 on ICS? Say it ain't so!
I use a Galaxy Nexus as my main phone and the Transformer Prime is my main tablet, so I spend a substantial amount of time using stock ICS.
