I just moved to LA and have sold my favorite computer I've ever owned..my 27" iMac. Its only been a week and I miss it. I got great value for it off of Craigslist. Man, I loved that computer.... I need something portable, and am debating between the Air and the 13" and 15" Mac Pro's, but can't decide what to get. I will not even consider the Retina's because of the ghosting issues that I've seen friends enounter, as well as the the price point. The lack of being able to upgrade really hurts it in my eyes. Maybe next year I'll take a look at it. I like the 15" setup with the High Res Screen. If I got a Mac Pro, I'd definitely add a SSD and RAM off crucial. I can't decide between the 13 and 15. The Air's seem pretty good too. I like how small they are, but they are close in price when you upgrade the higher end 13", and I can't imagine it being even close to the Pro, especially if you play the occasional game like Diablo 3. I use a ton of writing programs. I also play around with Photoshop and Final Cut, but that is just for fun, and I don't really need a machine at this time that is optimal for video editing. So, for those who have a good amount of experience with apple laptops, what is the better route? I've only owned deskstops from apple.
