There are lots of minor changes all over the place. The email interface is much improved! When you are connected to WiFi at home, if you have any Windows Media Center systems on the network, you can stream audio, video, pics, etc... to your phone. It works quite well. With Myn's ROM you get some incredibly fast performance. Screen transitions are fast and fluid. The music media player has a bunch of enhancements. The camera app has been changed so it's now very easy to switch between camera and video recording. Myn's has 720p working also, but no front facing camera yet. I was also reading in the HDMI mirroring thread that the beta app is working on Myn's Z, so you can get HDMI mirroring working as well. No 4G, yet. All in all it has been pretty impressive. It's really the only Sense based ROM that has my attention these days. CM7+4G was my daily driver but these littel improvements keep pulling me back to it. There are thing in GB that I miss when I'm on a Sense ROM and then there are things from Sense 2.0 that I miss when I'm running CM7. Good thing I can switch back and forth as much as I please... ;-)
