So, I'm making the leap (again) and re-switching to Mac. I had a G4 Power Mac back in '03 and wasn't pleased so I switched back but now I'm looking to switch to a MBP and I'm psyched. My question is, I hear there is a MBP update coming soon-ish. I know it is an opinion call, but I'm torn between waiting for the new ones to come out (I want a 13") and get my Education discount, or buying a refurb one now for a good rate. Any suggestions?
