i think im going to go with the MBP 15 or 17 so maybe i can keep it through college i just dont know which one ill choose at the store
You said you were considering the 17" MBP. That makes my hypothesise that your maximum budget is $2799.
For that amount you could get a 20" iMac ($1499), a base model MacBook ($1099) and 2GB RAM for each aftermarket (2x$85). Two machines for the price of one, one portable for taking around Campus and taking notes if you do an arts course and one with a nice big screen back in your room.
Of course, whatever you do, wait until after WWDC to see what updates come.
