Ok, I don't like COM5 23502. The supposed volume control improvements are minor. I'm not even sure what's better. But you lose the bounce back when you scroll on a list (ok, not a huge deal) but I just discovered on a menu that there was no kinetic scroll at all. I had to keep moving with my thumb and dude, that's a recipe for pain. I really hope MS puts that back in cause that's a deal breaker for me.
Just some random thoughts for whomever
