3DOSX is incredible. Totally worth the download, and some fun play time. However, at this point, I wouldn't say it's totally worth using. ;-) It's clearly just starting, and is very cool, but not nearly functional enough yet.
The good news is Nicholas Riley is among the people working on it. That means it's bound to kick ass as long as he's still involved. :-)
Ha! I posted this and noticed Nicholas responded to my earlier post about Fink just a few minutes ago, to warn me (and you) that there are errors in the tutorial. Thanks!
