Amazon put up a product pre-order page for Tiger, Apple's OS X 10.4 operating system, and it shows a March 31, 2005 release date. Price is the usual 129.95 like previous iterations of OSX. As far as we know, this is the first time a release date has been associated with the new operating system (Apple had previously said only that it would be out in the first half of next year). The date makes us wonder, though - March 31 is exactly the end of the first quarter of 2005, so chances are it's an educated guess by the Amazon people looking to line their wallets ahead of time. The other interesting tidbit is that one would expect Apple to release new hardware with the new OS, at least that's how it's been done in the past. As for what that may be, we'll just leave that cat in the bag for now and let the fanboys speculate.
