I know there have been a ton of these threads, but perhaps my question is a bit unique. I have the opportunity to basically trade my like-new 13" 2011 MBP (base model) for a 2010 11" Ultimate MBA. Is this a fair trade? USE: I will use the machine mostly for websurfing, youtube, email, light gaming (CS:S), etc. Nothing heavy like video editing or anything. EDIT: I'm not that mobile ATM, but I like to carry a computer around the house with me. Also, I had a netbook as my portable PC for the last year or so. (I would actually be selling mine and buying the MBA seperately) Is this a fair even trade? Am I winning in this trade? Thanks!
