Hi all, Long time lurker, first time poster. I'm starting in September. Will be purchasing an rMBP in mid-late August: 1. Top non-custom 13-inch: 2.6GHz Dual Core i5, 8GB, 512GB, Iris or 2. Base 15-inch: 2.0Ghz Quad Core i7, 8GB, 256GB, Iris Pro Main uses will be heavy web browsing, Skype/IM, report typing, and watching movies/TV shows in HD. I "shouldn't" be playing light games (e.g. LoL) but do like to know that my mac is powerful enough to do so. I intend to be running Windows on it as well, not sure if that should influence my decision regarding 256GB vs 512GB? When writing reports, I'd like to have a browser open on the left-hand side and Word open on the right-hand side. Can anyone tell me if they do this on their 13" rMBP and if this is a viable thing to do? The main issue I'm having is portability vs. performance. Price is not a factor in this decision. Suggestions/advice? Which one should I pick? PS. I'm pushing the buy date as much as possible in the hope of a minor spec bump/price cut to the rMBP line, but I must have it mid-late August.
