When IBM and Microsoft realized that DOS was out of date and needed to be improved, they began developing the next generation system: OS/2. Microsoft later decided to do Windows instead, but IBM continued with OS/2. Windows sold well thanks to Microsoft's forceful marketing, even though OS/2 beat it hands down on the technical side. OS/2 achieved true 32-bit operation with an object-oriented graphical user interface long before Windows, and is still far more stable (at one stage over 75% of all bank transactions world-wide ran on OS/2) and better at multitasking. In addition to native OS/2 software you can run almost any DOS, Windows, REXX or Java software -- including versions of DOS and Windows no longer supported by Microsoft -- and a wide variety of UNIX software has also been ported.
Since IBM stopped developing / selling OS/2, much of the development has been done by volunteer programmers in the Open Source spirit, rather like Linux. Even the latest version of OS/2 will run quite happily on a first-generation Pentium (e.g. 75 MHz, 32MB of RAM), so if you have 'upgraded' to something sexier including "free" (?!) pre-installed Windows, why not install OS/2 on your old machine and experience how operating systems should really be written?
To find out more I'd recommend a trip to OS/2 Warp.Be and OS/2 World.
I actually used Japanese OS/2, as it gave me English DOS, English Windows, English OS/2, Japanese DOS, Japanese Windows and Japanese OS/2 programmes ... all running at the same time, efficiently and safely. With Windows I sometimes had to reboot 25+ times in one morning. (Unfortunately, 'market pressures' have made me conform and use Win2K for my work, as that's what all my clients use.)
