I needed to upgrade my MacBook 2009 and was considering a MacBook Pro or an SSD drive. I chose the SSD drive (OWC). I'd heard how much faster they were, but I can hardly believe how much of a difference it's made. It feels like a completely different computer. In fact, now my Mac Pro early 2008 seems kind of slow (at least in terms of responsiveness). The Macbook boots up in like 20 seconds. It's almost faster booting up than it was waking up from sleep before the SSD. Best $300 I've spent on a computer. Now I'm thinking of getting an SSD for a boot drive on my Mac Pro.
