The Register has a great look at the development of OS/2, with all sorts of interesting little tidbits.

Microsoft developers on the OS/2 team were promised a week in Hawaii if they got the thing finished and, of course, had share options. IBM tried to compete with a trip to the Azores, which wasn’t quite as good. It was irrelevant anyway because Big Blue’s HR vetoed our prize on the grounds that IBM rules prohibited that many IBMers being on the same aeroplane.
