Dilemma: upgrading to a new MacBook Pro (that would be basic 13'' for me, but with a 128GB SSD) or switching the HD to a SSD in my old BlackBook (see sig. for details)? I wouldn't want to bring the RAM over my current 2Gb (not worth getting two 2Gb sticks to only gain 1.3Gb), so maybe I'm better off ordering a new MBP with 4Gb Ram and 128Gb SSD? What's a good but reasonably priced 128Gb SSD that would fit into my BlackBook? Thanks!
