hi, I'm new to mac. I just recently got a 12" PB. I downloaded MSN is how come its so much different?!?! I can't do winks, make contact groups, and i'm missing a whole lot of features. Am I missing something? Also I would like to ask just in general why are the USB ports on the left? whats the point of my Mighty Mouse since I'm right handed and most are (i think). anyone else annoyed with this?
