Yep, I own two of them. A 60GB as a system drive for my desktop and a 120GB for
my laptop.
The performance improvement really is remarkable. And its not the burst speed
that is interesting but the random access transfer rates.

The read performance is actually mostly limited by the host interface (SATA3 is
up to 600MB/s nowadays) and the memory management of the SSD, write perfomance
largely depends on how fast the flash cells can be programmed.
