Half truths and inaccuracies.
http://en.wikipedia.org/wiki/OS/2
OS/2 2.0 was the basis for BOTH NT and OS2 3.x (and 4.x etc)
It was co-developed by Microsloth and the big blue elephant.
OS/2 3.0 was in beta when M$ pulled the pin and was a joint exercise up
to the divorce (which is to say the vast majority of the code - the main
change post break up was IBM did further development on the GUI.
NT had many of the same underpinnings as OS2 2.0 - the key difference
was the GUI (a 32 bit version of the Windows 3.1 interface) NT 3.1,
3.51, 4 and Win Server 2000 all retained support for OS/2 binaries; and
a concept that was bought over from VMS in the way that virtualisation
was setup.
What became NT was supposed to be OS2 3.0, instad IBMthen developd 3.0
thmselves (along different lines to MS - more as an extension of 2.0
then a new technology direction).
The DC developers were the ex VMS guys Cutler bought across, and he's
the reason there was both a level of VMSsupport in NT as well as th
development of NT3.51 for the Dec Alpha in 64 bit

Rather inaccurate MS and IBM co wrote OS2 2.0, it was post it's
completion that they split up. The IBM and M$ versions are the same
product. Same as a Toyota Lexcen from the early 90's was still just a
commodore.
They dropped support of OS2 primarly because IBM and M$ had very
different marketing aims - IBM wanted to use it to tie people into
buying their hardware (hey it worked on the mainframe, why wouldn't it
work on these pesky little PCs ?). Unfortunately IBM never really GOT
the PC market. IBM's goals would have rather constrained M$'s ability to
make money - the split had nothing to do with technlogy and everythingto
do with money and power.
The OS/2 saga is a classic example of the importance of understanding
your market and making sure you are strategically aligned with your
partners.
Doesn't matter whether you have the best technology you have to meet
other customer needs as well (and being free to choose your hardware
supplier was too important to PC buyers - the IBM PCs were always too
slow and too dear)
