Received my 4GB card today from flashmemorystore.com. Plugged it into a reader on my PC and sure enough, 4GB, yay!!! Installed in my PPC and it only showed as 2GB. Soft reset, and viola...4GB. Now to copy the stuff from my 2GB card over to the 4GB card and really take it for a test drive. I'm going to try this without partitioning the card and see what happens. Will post experience in a couple of days.

As far as the vendor, straight up, one of the best online vendors I've dealt with. Package was waiting in front of my door when I got home from work today.
