Re: What problem will it solve ?
The OS/2 subsystem does some things that many other OSes have been able to. It also comes with a slew of excellent terminal emulations.
Admittedly, you probably won't need much of this but there are still a few companies with an extensive OS/2 landscape, who've saved tons of money by sticking with it.
I think that if I wasn't using MacOS I'd probably have a machine that could boot into OS/2 as I don't know how long it would before I hosed whichever unix I installed. The WPS really is quite funky.
