I've often wondered what happens to the thousands of retail copies of software when new versions come out. If I go to Fry's, I can't buy Windows 98SE, only XP. But what if Windows 98SE has all the features I need in an operating system? What if Office 97 would be perfectly suitable for me? What if I'm building a cheap computer for my parents, and they don't need the latest version of software? Other than Ebay, are there any places to buy sealed retail versions of older software? It's certainly easy to find old games, but older OS's and productivity apps seem to disappear on the appearance of new versions.
