I moved straight from Windows '98 to Windows XP, then added SP2 to it.
I run it in "Classic Mode", (Win '98), and find it simple, uncomplicated, and generally problem-free, compared to the reports of the Windows versions which followed it.
...and, very importantly, all my various (old) programs which I use daily, are written for it!
Internet Explorer (8), I find, runs very "sluggish" compared to Mozilla Firefox.
Sometimes I have to swap Browsers to get certain programs to run successfully....eg: Videos, etc...

...!
