I went to purchase a number of iMac 17" systems today and ran into an low quantities and out-of-stock problems. First at Comp USA. Then a Mac authorized seller would not confirm or deny if they would be getting any more in -- or when they might get more systems in. Including 20" systems. Apple store said they could sell me the 7 they had in stock, but advised me to get the rest online. Manager did not know when more would be arriving. Does this mean a definite GO on a new iMac G5 system at WWDC????
