I personally think the hypervisor architecture of 9x and its predecessors (starting at Windows/386) was far more interesting and innovative; while Win2k and the NT line are "traditional" OSes, 9x and 3.x are effectively VM hypervisors that have default hardware pass-through. DOS applications had dismal performance on NT, if they even ran at all.

The pre-NT Windows architecture was interesting for its "hack value" (remember that expression?), but as a user, even a technically minded one, reliability and absence of arbitrary limitations was more important.

DOS-based Windows had two main things going for it at the time, for users: It could run on average computers, and as you mentioned it could run most DOS software - most worked from Windows and all by simply stopping at DOS in the boot process (I almost always did the latter, I had no excess performance to give away).

Your comment reminds me (no insult intended) of the old adage that every doctor has a favourite disease.
