I’d never really though of combing VirtualPC and ReadyBoost.  Apparently there is a noticeable performance increase — so it appeals to me in a big way.  On a side note, Jeff Attwood has some great info on ReadyBoost.

Anyway, back to ReadyBoost and VirtualPC, check out more in Chris’s post “Vista ReadyBoost“, a snippet is below:

Went and bought a nice and fast 4 GB SD card (150x, 22.5Mb Read, 12.5Mb Write) and put it in my laptop.

After running with this turned on for a couple of hours now I can honestly say my laptop is much snappier when running a hefty VPC.

… but for running VPCs it seems really good. The card was less than $80 USD … a pretty cheap price to pay IMHO for an easier life running VPCs (my bread and butter).
