Why are hybrid Harddrives using the flash for cache?

This would be why I would want one. One that has it's own cache of like 32MBs and uses the flash to store the OS and program files and uses the hard drive for the swapfile and general storage.
Why are they not doing this?
 
most of the hybrid drives so far have about 256megs of cache, not enough for an os (outside of some small linux variants), sound like you want a hard drive with an ssd built in for the os/programs? Eventually you might see something like that, but by then you probably would be better off with a small ssd for programs/os and a large standard drive for the rest. Also you would want the swap on an ssd or cache (much faster seek).

that doesn't make much sense to produce, it makes more sense to sell the SSD and spindle drive seperately. not to mention you need to have a single company own both and an order of magnitude more complex controller...

this will never happen.
