OK so it was not actually a Kingston memory stick that I got given for Christmas. But this 8GB beauty has changed my work laptop from OK to great. I stuck it in and the option window came up asking me if I would like to use it as readyboost. What the hell I thought lets go for it.
Windows configured 4GB for the functionality and bingo my pc was zipping along. I am one of those users that has a lot of windows open and switching between them was slow.
If your PC is going slow and you have Windows 7 then give it a go.
