Hi, I am changing my workfield from desktop to mobile. I can probably can exchange my Mac Pro (2x 2.66 dual core Xeon, 3 Gig RAM, two harddrives, 250 and 500 Gigs) that i bought in september 2007 at an Apple reseller for a new, previous model Macbook Pro (15.4", 2.5 Ghz, 2 Gig RAM, 250 Gb HDD, matte screen) without having to pay extra money. (It's on sale for 1399 euro now) Would this be a good deal I don't want the latest model because of its glossy screen and it not being compatible with my 23" ACD as my main screen. How is your experience working with a laptop, compared to a desktop machine anyway? Will i experience a lot of difference in speed? I mostly work with CS3. Is backing up wirelessly possible/advisable?
