A few things I have noticed so far...(running the debloated leak)
Pros:
-Better battery life
-Smoother, no jittering like on the official stock 2.2
Cons:
-Streaming music is a problem. I have only tested Pandora, but it cuts off, halfway through a song. Google music streams fine with no cut offs.
-Ambient light sensor seems to not function, I have to keep my brightness all of the way up for when i go outside.
Other than that I haven't checked GPS functionality at all. Seems to be very close to final.
