I just thought of something... now that the Mac Pro is here, are the Apple Stores going to be selling off their many G5 towers at rock bottom "demo" prices?
I bought my PowerBook G4 as a demo for $300 less, so I know they do it.
My apple store (Stoneridge in CA) is having a fire sale right now. I was there on Saturday and there were a lot of computers out. None of them were diplay units, all returned stuff for $200 off. Mostly MBP's.
