Complete nonsense. Macs in the late 90s were awful, and most Mac fans I know agree with this, at least in retrospect. Slow, expensive, hardly any software ran on the things.

Windows machines thrived for many reasons, including being faster, cheaper, having the best office programs, by far the best games, as well as all the advantages they had in enterprise.

I don't think any competent observer could say that late 90's Macs were good value machines.
