It all depends on what you need the computer to do and what level of speed you're comfortable with. The G3 is still a good computer for email, word processing, cruising the web, and running spreadsheets. Heck, in the lab I work in, we have several Intel 486 66 Mhz computers running Windows 3.11. We need the computers to run some analytical machines. That's all the horsepower we need to do it, so it makes no sense to upgrade to Dual Cores or anything like that. So, there's still a need for older legacy computers--it just depends on what you need.
