Was thinking about this last night. I'm not a huge fan of the buttons. I like that they're touch sensitive, but don't really like the way they look. They remind me early iPods (didn't have a good experience with those). A very minor thing, and certainly not enough for me to not get the phone, but I like the looks of the HD2s physical buttons better. I'd also LOVE to see all of the red in the pre-production phones replaced with yellow. Represent!
