64-bit computing -- a decade ago

Very odd that Apple should claim that the Power Mac G5, announced today, features "the world's first 64-bit desktop processor". DEC announced the 64-bit Alpha processor back in 1992, and it certainly sold desktop PCs running the chip -- machines that looked exactly line Intel PCs, and ran Windows NT, in about 1994. Other firms put 64-bit MIPS chips, such as the MIPS R4200, in Windows NT machines. These weren't expensive chips -- you could get an Alpha 21066 for $186 -- though they still didn't sell. Still, ignoring Windows NT, I guess Apple wants to distinguish between old 64-bit workstations running Unix and new 64-bit Apple desktop machines running, er..., Unix. The main difference being that Apple doesn't actually have any 64-bit software.
