Thanks for the links. The articles are a bit dated, and don't pertain to Windows 7. So this is why I wanted to explore ReadyBoost, to see if there's any improvement in my system. I've already have 4 gigs of memory in my system, and that's all I can use with my 32 bit version of W7. So if I can boost memory a little using ReadyBoost, or if nothing else add a little more stability to my system, then it'll be worth it. It's really no big deal as a 4 gig USB flash drive only costs around $ 7.00.
So far I'm not noticing any major change, but my computer is running very smooth.
