My budget is around £1400 and with my work discount I can go as high as the lower 15" model. The difference in screen size between the 13 and the 15 doesn't matter to me. Just wondering what people think of my choices. Option 1: 13-inch 2.9GHz dual-core Intel Core i7 (Turbo Boost up to 3.6GHz), 8GB 1600MHz memory, 750GB 5400-rpm hard drive, Intel HD Graphics 4000. Buy a 256GB SSD from Crucial and replace the HDD. Total cost £1353.71 Option 2: 15-inch 2.3GHz quad-core Intel Core i7 (Turbo Boost up to 3.3GHz), 4GB 1600MHz memory, 500GB 5400-rpm hard drive, Intel HD Graphics 4000, NVIDIA GeForce GT 650M with 512MB of GDDR5 memory. No upgrades to any of it. Total cost £1408.80. I will mainly be using it for web browsing, iTunes (streaming via Apple TV), streaming online HD video (Netflix, MLB, NFL etc) and mirroring to TV via Apple TV, light video and picture editing etc. Anyone's thoughts would be much appreciated. Thanks.
