I currently have a 13" MacBook Air - Ultimate 2010. I'm a student at a university and enjoyed having the Air for its portability, size, and power. However, now that the 2011 refresh has come out, the price retention of the 2010 models have fallen dramatically (I purchased my Ultimate in January for $1,800 and now you'd be lucky to get $1,200 on eBay.) That's a devaluation of $100/month. So, my question is, sell my MacBook Air and upgrade to a 2010 MacBook Pro 15" or just keep my MacBook Air? I use my computer to: -Play games (WoW, StarCraft 2, and soon to be Star Wars: The Old Republic) -Microsoft Office - Word and Excel mainly. -Browse the internet -Watch Netflix. -Listen to Music. -Watch YouTube videos. -Other general things. Is it worth it to sell my Air and spend $200-500 more on a 2010 15" Pro for the added GPU and CPU power, battery life, resale value, bigger and better screen? Open to suggestions!
