One advantage of MacBooks over PC laptops is they tend to hold their value a lot better because Apple don't release a low cost model with better specs 18months later.
I got a refurbed MacBook from Apple a couple of years ago and it has been great, does everything I want from a laptop and will run windows in VM too, which is handy. The touchpad is a joy to use (I want to throw most laptops out of the window after 10 seconds unless I can use a mouse).
Main differences between MacBook and Pro:
Pro has bigger screen, better specs, more connections (firewire etc) and an alu case (although I think some MacBooks have them now).
If you don't need a big screen and you aren't doing intensive image editing I imagine the non pro would suit your needs.
Ta. I will be going for the smallest (13 inch) version for portability, think the alu case is lighter too. Don't really care about the resale value as once I have it I'll keep it till it dies, which my current lappy will do soon...........
Got my lad one recently for his 2nd year at Uni (13in pro), thing of beauty with excellent screen (bright in the lightest of conditions), usability and keyboard. Make sure you get the 500gb of storage option (cant get in a shop - only online). If you know of a uni student they get upto 17% discount (+ massive discount on apple care) depending upon which one they go to? I also got the current free Ipod touch and printer offer (rebate).
In my experience PS, FT and Betfair clients work very well. Only slight issue is that Poker tracker has to run in VMWARE based XP image, but with MacPro its no problem. Enjoy and there will be no going back to PC's !!
