Ok folks, here is the deal. I will be attending college in the fall and will be majoring in Computer Science; therefore owning my own computer will be a somewhat must-have. I do not own a desktop, nor will I be buying one, so I would like to get a 15' mbp to act as both my desktop-replacement and portable class computer. Will Apple be introducing a new variant in the fall, say around sept-oct? I can make my Ibook G4 last a couple of months in the fall, so its not urgent that I get a mbp for the first couple of months. Do you foresee apple releasing an upgraded mbp sometime in the next 6 months? Should I wait for the 2010 USB 3.0 variant? I HATE buying computers might before significant updates. Thank you!
