Re:That would actually be the major reason not to (Score 1)

I don't think this directly applies to OS/2. I used it back in the day. It was a better Windows than Windows. But it really had no native apps to begin with (OS X has an awful lot). It also wasn't readily pre-installed on any hardware (as OS X is). You had to go through the trouble of wiping your computer and putting it on it. And it had limited driver support, so you had to carefully select your PC. Not things that would encourage widespread adoption. I don't think we would even be talking about OS/2 today if it hadn't done Windows. It would have disappeared quickly and quietly.
