OS/2 was a really solid OS but the DE was frustratingly too 'close but no cigar'. I never figured out if it was because the design and implementation team was pulled off before the thing was fully baked but while everything mostly worked you were constantly butting heads with how they had implemented the OO desktop. I mean it should have worked but too often it didn't and then I'd spend too much time trying various work arounds. Shortly after it was released I bet the farm on OS/2 eclipsing Windows, and then spent several years beating that horse until I finally had to accept that IBM had made too many boneheaded decisions. IBM literally was incapable of releasing a usable, appealing OS for PCs. Just in the same way they tried for years to sell PCs but ultimately had to walk away form that business. There's been lots written about the flaws in the IBM mentality so I won't bother to try to add my own spin here. If Warp had been released earlier they may actually have had a chance, but by the time it was released OS/2 was a standing joke. Pop!_OS is currently my favorite DE, by a considerable margin. Over last Christmas break I thought I'd give it a look one day when I had nothing better to do. Within a week not only was I running Pop on my production box but I'd switch over to it for gaming too. I can dual boot to Windows if I need to but I literally haven't needed to for months. Hats off to the Pop team over at System76.
