Wordperfect was crap compared to MS Word.
Lotus, same compared to Excel.
DR-DOS was niche and more expensive than Windows which did the job.
OS/2 was even more expensive than Windows.
If IBM released OS/2 with DOS and Windows compatibility for less than Windows, it would sell. As it were, it was corporate greed that killed it completely. In Poland, IBM desperately tried with advertising when OS/2 Warp was released, but trying to sell for twice the price of Windows NT (not to mention consumer versions) meant that even with mostly positive reviews, it was doomed from the start. Microsoft Windows also offered significantly better Polish language support as opposed to OS/2, where it was supposedly the only truly negative aspect.
IBM decided that they would compete on features, but having more features does you no good when you can't read the screen text because it's garbled.
Biting the hand that feeds IT
