I installed cm10 two days after i received the phone. There are a few annoyances, but i get good battery life, can run almost two days.
gsm and 3g works perfect, call quality is good, 3g speeds are decent, in my area i get about 1.1 mb/s down and 300 kb/s up.
System runs smooth and fast as default.
The things that annoy me is the bug where volume rocker doesn't wake the device, mentioned on first post.
Some sounds are too low, Alarm sounds compared to my Desire are lower, unlock/lock sounds as well.
When playing music, all info on lock screen is hidden, so you can't see time, weather or scheduled plans.
When you pause music from the lock screen, after about 3 seconds of silence, it'll play another 2 secs, then go silent again.
But, overall i'm happy, a few kinks which i'm sure they'll fix. It runs really well which is nice.
