In the end I am glad OS/2 did not make it. Although it probably still is better than windows 8, if IBM would have had success with OS/2, they would not have invested time in linux.
Now there is just one common "enemy" with still a lot of anti-competition lawsuits, and one common linux in which about every company is investing.
At the time i was quite annoyed that a better system would fail due to bad software support and marketing. But you make a very good point, looking back it was actually a good development for Linux and the Open Source World.
