Originally, i bought the ipad 2 to hold me off until apple redesigns their MBP (i'd sell the ipad when the MBP is released).. but the more i think about it, the more i like the idea of just getting a IMac and being done with it.. obviously wait for the refresh though. using the ipad for college (notes and web surf, etc.) and come home to do homework assignments on the imac. cost wise, it seems efficient too.. $750 ipad + $1500 21.5" imac = $2250. or $2300 15" MBP thoughts?
