If you're running win98, why not run DOS? Better yet, why not run C/PM and write your own web browser in assembler?
Uhh, windows 98
has DOS in it, and also restart in MS-DOS mode. Much more convenient.
And if I ran just DOS 6.22, I wouldn't be able to run opera 10 in it... nor would I have the nice interface to select which MIDI canvas I want to use.
I have 384 MB of EDO RAM; it would all be wasted if only running DOS. PLUS, I have win 9x-specific games and whatnot.
As for writing a web browser on C/PM... why don't you go do that? It takes a lot of resources to write one, not to mention time.
