No, not really. When I was comparing prices, the Mac Laptops were 3 times as expensive as the PC. I felt the Mac also didn't offer as much, so I went with this one. It has everything I wanted/needed and some bonuses.
As far as OS goes, if I had a choice I would like to have XP on here. OS X is fine and all, but I just prefer XP. CS3 runs about the same speed on my laptop as the Macs at my school so I see no need for Mac.
