When I bought my MBP, I used it quite a bit for gaming. I used to play World of Warcraft, and I would boot into Windows 7 for Star Trek Online. I may boot for STO in the future, but my WoW playing days are over. I take this computer to work every day, travel with it, and use it for watching/converting videos, office documents, web browsing, e mail, and education mostly. I would like something a bit more portable, as the MBP is heavy. Seeing as this computer is a year old, how much do you think I would get for it on eBay? There are two very minor scratches on the bottom of the device. I've been treating this laptop very well. Is it even worth it to switch to an MBA 13" at this point? The smaller computer would be much better for carrying around on a daily basis, but how much performance would I be sacrificing considering the extra money I would have to put in after selling the MBP?
