I feel that the performance gain still isn't worth the price premium and the tiny relative size of the drive... I could almost get 3 x 1TB drives for the price of a single 64GB SSD. For what I do, the performance increase doesn't justify the extra price for so little space... I felt the same way about the Raptors when they came out.
If I ever feel the need to try to open 50 programs at once, however, I'll be the first in line for a SSD. It's impressive to be sure... but it just doesn't translate to real-world performance.
