I just did a little more research and apparently, the life cycle is up to around 1,000,000 write cycles now. Oh, and ZPB, the term you are looking for is "wear leveling".
Not quite the same thing as I was originally thinking, but TRIM is what it's called, actually for cleaning up blocks and doing smart erasing, keeps the drive performing faster over time than one without it.

Yeah, TRIM is something different. And if I'm not mistaken, the OS has to support it too. Also, TRIM is required if you want to encrypt the data, or securely wipe the data.
I just recently got a Kingston SSDNow V series 64GB drive for my graduation present. It was $112 after the rebate (they have another deal going at Newegg right now for the same drive for $115 after rebate). Gosh this thing is amazing! Windows 7 boots in 30 seconds consistently and programs open instantly. Haven't really had any crashes yet, though haven't had the drive very long. I didn't notice much of a difference for games like Just Cause 2 and DiRT 2, but something does feel a bit faster about them. I've got my 1TB drive to hold all my extra non-program data. Just gave my extra 750GB drive to my brother because his old 120GB IDE drive was very full and slow lol.
I'm really hoping that SSDs come down in price and up in capacity, as I'd really like to have a 128GB drive for my main system drive and a 256GB drive for my laptop. The speed and access times of these things are just insane.
