It actually did take off for a while, and it won a lot of awards, but when IBM pulled the plug on what little support it was giving the OS it became harder and harder to stick with it.
I used it as my primary OS between mid-1992 and 2006 or so, but once the magic smoke leaked out of my primary PPro box I moved to various Linux flavors. I really miss the WPS and my old 4OS2+FileJet command line setup, but Midnight Commander and bash can also make me happy. :-) And I have to admit that the FOSS ecosystem has far surpassed my expectations. Linux distros have come a looong way since the mid-90's. Edited 2013-02-12 23:13 UTC
