i'm actually excited about the new trackpad. i have some kind of a weird sensation whenever i use a silver trackpad, a sort of tingle in my fingers. this doesn't happen on the magic mouse's white surface... anybody know what i'm talking about? my friends think i'm crazy.
i've been using only the apple trackpad for about 3 years now, and the "sensation" you describe was persistent for the first several weeks / months. the interaction by using the tip of your fingers is a bit wierd at first, but now i could never go back.
trackpad is very superior to a mouse, at least for non-gaming stuff, like coding & browsing the webs
