Ammar,
Yes, the speed increase is amazing, however the drives are still too expensive. The hybrid drives are cheap (in comparison to SSD) and provide an increased performance boost. At the moment, 60 Gigs wouldn't be enough just for my programs and data, so there is no way I can move to a SSD solution, not at least their prices come down.
Correct to my previous post, the hybrid hdd I purchased is not a 320GB, but a 500GB.
Cheers,
