It's already got its own toilet paper in Japan, but the rest of us are still patiently waiting for Vista SP1 to officially hit -- but maybe not for much longer: DailyTech is reporting that SP1 will be available for download starting tomorrow, with boxed copies to follow on store shelves Wednesday. While Microsoft's PR team wouldn't confirm anything other than "on track for mid-March" to The Register, it seems the company has been a little more forthcoming with its pals at Amazon, which is also listing March 18th as the release date for SP1. That's some fishy fish, but there's only one way to find out for reals -- nap time, here we come.
