With Windows98, Gates is on target. Windows98 runs faster than 95 and adds features. The answer depends on a lot of factors, but a significant one is how often your current system crashes. A crash is like a washer stopping in the middle of a cycle. If your system crashes several times a week, you certainly should move to something else.
Crashes are legendary.
Windows98 should be more stable than Windows95. But if you have a computer that can handle Windows NT, consider getting that system. While we are not a typical setup, I like NT and would just as soon skip over Windows98. A key decision must be made when a server is purchased. NT is an easy and stable server choice for most offices, particularly smaller offices.
