That settles it.
I'm buying a Mac.
I hope to have one (or both!) of my old Win 98 boxes running at least a dual-boot with Knoppix Linux here in the next few weeks.
Ideally, I'll have learned enough about Linux to make them exclusively Linux boxes.
If you ever need any technical assistance, we have some good Mac experts on the forum. I hope it will be an enjoyable first-class solution for you.
