Upgrades from Microsoft's past have also colored expectations, Silver said. Users tend to remember the straightforward transition from Windows 2000 to XP, even though technically it was a "minor" upgrade, he said. (Silver also noted that until XP Service Pack 2, XP had its own share of compatibility and security flaws that annoyed users, something that most forgot with SP2's release.)
And while the path from Windows 95 and 98 to Windows XP was rockier, the benefits were clear enough at each stage for most customers to make the upgrade investment gladly, Silver said.
Some users have decided to skip Vista altogether and instead wait for Windows 7, whose release date has been reported as anywhere between 2009 and 2011 "Why shoot yourself in the foot twice? Windows 7 will be out next year; I'll wait till then," said one InfoWorld reader. If Windows 7 arrives sooner rather than later — or if a miraculous Vista service pack addresses all the major objections in one swoop — then the uproar over upgrading to Vista will quickly fade into the hazy past of other Windows upgrade snafus.
