I currently have a last gen 15" uMBP with SATA 3.0. Macrumours mentioned that the new uMBPs have only a 1.5 SATA interface although you wouldn't notice a difference unless you used solid state drives. I eventually want to switch to SSDs when they reach 512GB and are somewhat affordable. I'm curious if I should just hold on to my current MBP with the 3.0 and the expresscard slot. I want to buy a new unit so I can get the matte screen. Any comments are appreciated.
