I've had an SSD in 2 of my laptops for a couple of years now.
Whilst they're considerably quicker than a standard HDD, there is one massive downside which has bitten me in the bum twice: If you lose your boot sector info, you lose ALL data on the rest of the SSD and there's NO getting it back.
(and yes, I did have backups for most things, but finding that the SSD firmware was incompatible with my Dell Latitude E6500's hibernate function at 2am whilst waiting for a remote server rebuild to complete was not my idea of fun....having the SSD wipe itself and having to reinstall Win7 asap in order to complete the server rebuild before the users came in in the morning was a bit hairy to say the least).
