OS/2 was owned inside IBM by the networking division...
This can let you understand a lot...
IBM never had a consumer mindset. IBM is Enterprises best friend and knows how to work with and satisfy them more than anyone else in the long term and across the board.
Missing applications were a big problem not solved with Lotus buyout (IBM bought Lotus for Notes). Do you know Sun's StarOffice comes from an IBM Germany division?
Many IBMers never belived in OS/2 even when it was the best. They never gave it a chance. It was easier to show the customer to be "open minded" and sell just PCs (more $$) then push hard for also selling the OS (very few $$). No vision in sales, no forced vision from top Mgmt.
OS/2 never had a father like Bill :VOMIT: Gates meeting with top customers just to sell Windows 95 :VOMIT: even investing in their shares to get them. He had the strategy and the vision. IBM had-has too many product lines. This can be an advantage here and a disadvantage there...

Bill is still playing the domino game and with President Bush he has good hands to be left free to play hardball.
Today, if I was a country (not USA), I would had never allowed my PCs/embedded/console/radar run Win-anything. Too many bugs, too many security holes, too many unknown "features". I'd rather had developed a secure-linux opensourced to know every possible detail of it and be sure it's not somebody's ears and eyes.
