Hi, Want to buy a MPA to replace my 5-year old macbook. My daily use are mainly on web browsing and online video streaming. I do need to run Parallel for windows system or some photo editing software occasionally, and these are probably the most demanding task I do. My budget is within $1300 and I'm not considering MBP because of its low resolution. I am debating in these two options: 1. MPA 13in $1249 (released in July 2011) dual-core Intel Core i7 1.8GHz 4GB RAM, 256GB Flash Storage Intel HD Graphics 3000 2. MPA 13in $1138 (newest version) 1.8 GHz Intel Core i5, Turbo Boost up to 2.8GHz 4GB DDR3 SDRAM, 128GB Flash Storage, Intel HD Graphics 4000 My concern for option2 is the 128G SSD maybe not enough to support dual systems. But for option 1, is it sufficient for my use? Thanks for your help!!
