Actually, Windows 98 (FE = First Edition), 98 SE (Second Edition) + ME (Millennium Edition) are *still* alive and well.
Please keep in mind that Windows 9x [95/98/ME] based OSes are installed on over 70 million computers, out of which 50 million are running Windows 98, 98 SE or ME.
Most small companies, charities, schools and a lot of individuals cannot afford to upgrade to Windows XP or any other OS, even Linux, because they don't have the necessary resources and/or knowledge.
True, Linux distros are free, but someone needs to install, service, repair and maintain [in many cases] a large number of [eventually networked] computers, no matter what OS they may run, and those IT technicians must get paid.
Sure, the KDE/Gnome interface may look familiar to most Windows users, but there will be a learning curve to make use of it.
Do you think people are willing to go through such pain just to upgrade their good-working 98/ME computers? Ask them yourself.
Besides, those good ol' 9x based OSes are fairly easy and cheap to maintain and troubleshoot, even if Microsoft won't help anymore.
The point is that...
Enthusiast power users, programmers and IT specialists provide *free* support in their spare time at various web sites, forums, blogs etc.
MSFN.org is the best known support forum for Windows 98, 98 SE + ME, and all updates, service packs, fixes, patches, enhancement packs etc... are free:

This way Windows 98/98 SE/ME OSes can be safely used even on modern, fast computers for every conceivable purpose, including playing hardware demanding games [if you have the necessary hardware that is

], desktop publishing, 3D graphics rendering, high-end A/V editing, CD/DVD burning, programming, internet browsing etc.
