I say wait for the vertex 3. I am. And my MBP is the mid 2010 and isn't Sata III. I plan on getting another computer as soon as a redesign happens. SSDs are simply too expensive to buy a current-gen with the excuse that you'll save 50 bucks, when sooner than later you'll have a computer that takes full advantage of the speed. Just wait til the vertex 3, use it, and then when you buy a computer that can take full advantage it put it in there and notice even better performance.
