I've been using wnidows ever since ive had home computers but i think im finally making the switch, I've decided I don't want to wait for any redesigns or any crap. but I can't choose between the 3 configs I've attached 3 screenshots cropped in on the specs. if I got a macbook I think I'd like the white. but im not sure how well it lasts compared to the blackbook... also if I paid the extra for the pro what would my extra £250 be getting me. I'm worried about the reduced wireless signal but the screen would be a plus. thanks for any help.
