OS/2
In 1987, IBM released their first 32-bit PC, based on 386.
At the same time, they released the next generation operating system, intended to replace DOS.
But... the new OS was still 16-bit, designed for 286.
And so heavy that it was impossible to run on brand-new 286 machines in stock configuration, and even on many 386 machines.
In short: doomed to fail.
So doomed to fail that, after launching in 1987 it had 3 subsequent releases until 1996 (arguably 4 until 1999, if you count 4.50) and every one of them is far, far superior to any contemporary OSs in the market at the time.
2.0: Amazing multitasking, virtual 8086 mode to multitask DOS programs
3.0 Warp: Basically a superior Windows 95 in 1994, Internet&TCPIP ready out of the box, ran Win16 software better than Windows
4.0 Warp: Windows 2000 in 1996
OS/2 being (mostly) 16-bit is a result of having to run in 16-bit protected mode on 80286 PS/2s, on which the OS was designed to run. This was fixed in 2.0 and 32-bit protected mode and virtual 8086 mode was added, in 1990 as I noted above, which coincides with Windows 3.0's release. Granted Windows 2.0/386 had this in 1987 but I don't know of anyone who used it at the time.
So, in the end, I'm sorry but I strongly disagree..
