ssd drives

Is anyone using a ssd drive as ther primary drive? I have been thinking about upgrading to a ssd for a primary drive and using the 1tb that came with my computer just for file storage. 128gb ssds have come down in price to around $100. 64gb ones are down around $60. Im thinking that $60 is a small price to pay for the performance gains and quietness and energy savings that the drive will produce. I think the technology has improved and the prices have come down to the point that its worth it to do so.
