Vista availability: Make that 'late January'

People pining for Microsoft's Windows Vista should circle the date January 30, 2007 on their calendars.

Prices for the various editions of Microsoft's next desktop operating system were leaked and covered on Monday. Later in the day, industrious bloggers uncovered more details, namely the ship date.

Until now, Microsoft has said that the oft-delayed Windows Vista will ship in January, 2007.

Eager customers can pre-order now from Amazon.com.

Full-copy prices are:

Windows Vista Ultimate for $399; Windows Vista Ultimate Upgrade for $259; Windows Vista Business for $299; Windows Vista Home Basic for $199.

Upgrade products (from Windows XP) and prices are:

Windows Vista Home Premium for $239; Windows Vista Home Premium Upgrade $159; Windows Vista Home Basic Upgrade for $99.95; Windows Vista Home Business Upgrade for $199.

Amazon is also listing a slightly-lower-than-upgrade price for "additional license packs." Those would appear to be for a second or third PC, but Microsoft would not comment on them, or Amazon's prices

Microsoft said that it will announce official US pricing when it issues the Release Candidate version of Vista, sometime next month.
