Windows Vista has a new feature that's designed to give users a quick, simple and cheap way to boost the performance of their Vista-powered PC - it's called ReadyBoost. But what is ReadyBoost?

OK, I've got a machine with a Phenom II x4 940 and 4GB of RAM. I've got an extra 4GB flash drive with a broken case, that I'm thinking I can devote to ReadyBoost. Is there any point to doing so ...

Fortunately, Windows Vista offers a ReadyBoost memory expansion feature for those of us who either don't know how to upgrade memory, or simply don't have the money or system capacity for extra memory.
