Today's review is about a piece of technology that was way ahead of its time. Also designed with an IBM selfish attitude. That went well.

It wasn't really like WINE. There were two different "editions," Red Spine and Blue Spine. Red Spine, the cheaper option, could use an existing Windows instance installed on the same computer to run native Windows applications. Blue Spine directly included support for Windows binaries. This is because Microsoft and IBM were co-developing OS 2. When they split, Microsoft took the code and developed NT. IBM kept going with it and released OS 2 Warp. Both NT and OS 2 Warp also supported running applications based on POSIX, which means that they could run Unix binaries. That support was disabled in NT by default. Also, NT could run native OS 2 applications, but again this was disabled by default.

Your information is incorrect. Windows NT is not a descendent of OS/2 Warp. OS/2 (not Warp) was originally a joint effort between Microsoft and IBM. What eventually became Windows NT was originally a project called NT OS/2, an effort to build a 'better', multiplatform version of OS/2. Part-way through the NT OS/2 project, Microsoft and IBM's partnership ended. IBM continued to develop OS/2 on their own. The result of their work was OS/2 Warp. Microsoft continued work on the NT OS/2 project, which eventually became Windows NT (due to the then-recent success of Windows 3.0). Windows NT 3.5 (the first version of Windows NT) even included support for OS/2 applications - a remnant of their work with IBM.
