Here: http://playdosgamesonline.com/doom-ii-hell-on-earth.html (yes, it's Doom 2, and yes it requires a fast machine since it emulates a DOS PC in the browser)

I can't help but add that it's a DOS PC + a game that still loads faster than some web pages. At some point, even the apples to oranges comparisons start saying something because it's glaringly obvious.

Ok, awesome. Now I'm wondering if we PCDOS in a broswer...

1) Can we say the claim (I think of mozilla's) that the web was going to be the new OS is true?

2) If DOS today, will it be 5 or 10 years before we get BSD or *nix in the browser?
