Hmm RAM

I ordered a one gig RAM stick for my PowerBook from newegg.com and it showed up today! 1.25GB is mighty sweet, I thought I could run Virtual PC with 768MB of RAM, which is more than my work laptop and I could maybe carry my lighter PowerBook with me to work instead, though it looks like the processor speed will be too slow and VPC only allows you to allocate 512MB which means that I won't gain an advantage. If anyone is interested in buying my 256MB stick that will nicely work with your PowerBook (I think it will work with iBooks too can anyone confirm or deny?)?
