OS/2 and eComStation IBM's OS/2 has a great history as a workstation operating system, it was a major alternative OS in the '90s. At its peak time in the mid-'90s OS/2 had about 2 million users but the Windows NT and Windows 95 releases broke its further development. This year Serenity Systems has released a new client version of OS/2. This article will introduce you to what OS/2 is all about. You will learn its history, its user interface, and its power under the hood. The article is also accompanied by a number of screenshots.

Timelines and user count wrong.

The article is good on the whole but is wrong on a few points. OS/2's GUI was released with version 1.1 (Dec 1987) and for that verion and 1.2 looked very much like Windows 2.x. OS/2 1.3 shared common GUI design with Windows 3.x. With the release of OS/2 2.0 in April, 1992 the TRUE object oriented Workplace shell came in to existance and it is from this GUI that all later OS/2 shipped* GUIs are based. (* This discussion could evolve with if one counted XFree86/2.)
Though the early GUIs shared a similiar appearance, I doubt that much of code base was common. Since DOS lacked many of the features OS/2 had at its core, the Windows code needed to perform a lot more work.

Numbers kicked around in my OS/2 user group at the time were around 13 million installed based for Warp 3...perhaps the 2 million value was the number servers installed since this was OS/2s primary market in the beginning.

Regards.
