Does anyone have experience with the new (at least on the consumer electronics market) solid-state hard drives? Now that they have predictably plunged from $600 to $150, I am thinking about self-gifting one as a replacement for the OEM 5400rpm shitball that came with my laptop.

The advantages in speed, access time, quietude, and power consumption of a drive with no moving parts are all obvious. Does it entail a trade-off in durability or longevity? I get the distinct impression that these things are going to obsolete existing HD designs in very short order, although the fact that defragging (which most OS are set to do automatically at some interval) destroys SSDs will probably delay their widespread acceptance.
