Carl Bialik from WSJ writes "When software makers urge upgrades, it isn't always in users' best interest, the Wall Street Journal reports. Many upgrades bring advertising or other unwanted features; some iTunes users felt this way about a recent upgrade. But for many programs, downgrading can be a headache--Yahoo generally doesn't link to old versions of software, and Apple says iTunes can't be downgraded. Some websites can help with the problem. OldVersion.com, for instance, offers more than 600 versions of about 65 different programs. The site's 16-year-old administrator says, 'Companies make a lot of new versions. They're not always better for the consumer.'"
