Anyone?
UI is quite smooth, lots of CM9 based ROMs and kernels available. Video recording doesnt work with the regular camera app, you have to use an app called Videocam Illusion to record at 720p or lower. Battery life isnt that good, and the ROMs tend to get slow after using for a few days. But dont forget the much better UI and awesome ICS feeling :yahoo: .
I'd suggest you to take a nandroid of your current ROM and give a CM9 ROM a try, worth an experience for some time. Owain's build, Mr. XXHyde's build, EGB team's build, and ParanoidAndroid by tonyp are some good CM9 builds. MIUIv4 by bihariel has the best looks i've seen so far, but is a bit more limited in functionality. Here are some screenshots I had taken while using MIUIv4
