Amazon.com has changed its Vista order pages. Vista's now "estimated to be available in early 2007." Vista ships on January 30 you say? Well…maybe. How about “Early 2007?” That’s the message today, after reports by InfoWorld, and on CNET and elsewhere yesterday that major e-tailer Amazon.com was informing customers that Vista would ship on January 30. (That’s a Tuesday, btw.) Ever the reluctant groom when it comes to taking Vista to the altar, it looks like Microsoft wasn’t comfortable being pinned down to a specific date, so now Amazon has changed the Vista order pages to say that Vista is “Estimated to be available in early 2007” which, depending on your definition of “early” could be anytime from January 1 to, say, May 31.
