I never experimented with OS/2, but a friend told me you could start running apps on OS/2 while it was installing! How's that for a superior OS?

I helped my dad install OS/2 Warp and we got everything running and he used it for a couple of years, until the drivers stopped being updated and eventually I told him he would have to go to windows.

As always, it is about getting hardware and software support. BlackBerry BB10 is a superior mobile OS, but it didn't get the right support and failed.
