I'll have to admit that I now know that I know nothing.
Back when I wrote the message you quoted all articles I had read about
ReadyBoost said it was just swapping on flash drives.
Right now after doing some research I'm a bit confused, because most
sites contradict each other.
It seems that ReadyBoost is actually a cache for about everything from
swap file over system data to often read user data.
I think it might be worth implementing if done properly (it seems using
ReadyBoost in it's current form in Vista can actually slow down the
system sometimes).
