If Amazon.com is to be trusted Vista Service Pack 1 will be arriving very soon. This listing for Windows Vista Business with SP1 Upgrade appeared on Amazon.com today. There are also listings for all four versions of Vista with SP1. Amazon.com is currently taking pre-orders, and says the boxed software will start shipping on Wednesday, March 19. According to Associated Press, “the retailer is selling copies of Vista without the service pack and advising customers that they can download the free SP1 upgrade starting Tuesday.” As a current Vista user, I have to say I am not all that excited for the “upgrade” since many of the fixes in Vista SP1 have already been released as part of regular monthly updates during the year. Sure, I have had my handful of issues with Vista over the last year, but time and time again I have called Vista my little sister. She is a real pain in the ass, but over the years you just learn to get along and love each other. What will SP1 improve? Microsoft says Vista’s reliability, security and performance. Looks like we will just have to wait and see.
