Looking to get my wife a new 13" rMBP, I'd be going for the 3 GHz i7/256/8 combo since I want it to last several years. Not thrilled that the RAM isn't upgradeable to 16, but oh well. 16 GB RAM would make me feel really solid about the purchase. How will this machine be with heavy flash usage? My wife plays animated flash games on a Japanese social networking site a good bit and I know it taxes my 2.66 Ghz i7 Arrandale 2010 15" MBP, with 4 gigs of RAM and a 7200 rpm HDD. Just want to make sure this machine will last a good while for her and won't bog down with flash animation sites? Thanks.
