So my sister-in-law is looking into buying a 12" PB, and we saw that there is a $150 rebate on Amazon. When I compared the specs to the current 12"PB's for sale at Apple.com, it seems the only difference was a 60GB hard drive instead of 80GB. I guess it doesn't have the newest version of iLife either. Is there any other difference in spec that I have missed? More importantly, can anyone tell me if the PowerBook always came with the QuickBooks software? Thanks!
