So, I did a cursory search for this topic and didn't see anything, so I apologize if I'm covering old ground here. I'm gearing up to buy a new MBP. Picked out my machine and set the money aside, but then someone gave me a $250 gift card. Was thinking about using that to justify getting the 128GB SSD. I store all my media on an external, and have about 20GB on my powerbook's HD, so space isn't much of an issue. Is there a catch, other than the high cost per GB? Any known glitches, etc?
