Oh I dont think they'll be able to sell them at 500 Euros, the price will be dependent upon the processor installed, and how soon it comes to market, because G4's are dropping in price. But right now with a 1.7 Ghz G4 (what they are touting) that board is 4 figures US at least, and then we have the OS 4 tax tacked on. Or you could get a 1.42 Ghz G4 Mac Mini (whole computer) for $600. Its silly that after a year of no hardware availability and a shrinking installed base for the OS, they still have no real plans, and are hoping to use an expensive motherboard to move the OS forward.
