Isn't flash more expensive than RAM? So why not just add 512M RAM and run your swap in ram?

The problem is that flash drives are fast at reading but an order of
magnitude slower at writing. Also flash drive cells have a limited
number of write cycles before they go bad. Some flash drives are smart
so that they rotate around where they write to even out which cells are
written to but they will eventually go bad and the size of your flash
drive will slowly shrink.
Microsoft Vista has a similar feature where you can plug in a flash
drive and it extends memory. I would think it would mean swap space
since even though flash drives are fast for reading they are no where
near the speed of the memory on the front-side bus.
