Considering getting an SSD for my MBP. 1) Will it perform as well as the Flash memory in a MBA? They load apps stupidly fast, will the performance of a SSD in my MBP match that? 2) Are they hard to fit? 3) I know there's loads of threads about this, but which would you recommend? I will be getting one for my dad's 13" MBP as well, will they both be the same size? Thanks a lot.
