They're not worth the cost.
A lot of the issues with SSD's are resolved with the new ones.
And with the whole concept of hybrid drives, Intel has a new feature with their Z68 chipset that basically makes a hybrid drive in software, using a normal SSD and hard drive. It works MUCH better then hybrid drives. And if your thinking "why would I shell out for an SSD and use this if using the SSD like normal is faster", it's because the feature is optimized for cheap/small/used/old SSD's.
I have a 60GB with just Windows and Office, about half free. You know the feeling of a brand new install, everything opens on the dot and such? It feels faster then that, and never goes away.
