So I want to make the switch. I REALLY want an iMac and a MacBook. I am trying to wait for the update for the iMac before I get one but I am trying to figure out the best configuration to have both. I have been looking at the white MacBook for a few months now. I need something that will be better then my current Dell POS. Current configuration: Dell XPS M1210 Windows XP 2 GB Ram T7200 @ 2.0 ghz 100 GB I want to have the desktop and laptop sync and have the time machine for backup purposes ( Ive had alot of bad luck in the backing up documentation area) Please help me figure out what would be the best configuration for the total package. FYI - graduating from undergrad in June then going on to Business School for an MBA/Masters and also working. I need to ability to be mobile and the discipline of sitting at the desk when at home (hence the desktop). THANKS!!
