It's official: Vista SP1 to be available tomorrow (Tuesday, March 18)

Thanks to a confirmation on Computerworld, Gregg Keizer writes that the release of Windows Vista SP1 will be out tomorrow...

"In an e-mail meant to clarify when Amazon.com could begin shipping retail copies of Vista SP1, a company spokeswoman noted that Vista users could get the update on March 18.

"When looking at Amazon's site, you will see separate listings -- one for pre-orders of Windows Vista with SP1 integrated, and the current version of Windows Vista, which does not include SP1, and can be purchased now and easily updated with SP1 online beginning March 18," the e-mailed statement read...

"If Microsoft holds to plan, Vista users will see SP1 in Windows Update tomorrow as an optional download, but only if their PCs do not harbor one of the balky drivers. Alternately, users will be able to download a much larger stand-alone installer from Microsoft's download site, also beginning Tuesday.:
