OS/2 Question and Answer

Q: Why would you use OS/2 when there are other operating systems out there that can use most if not all of the software OS/2 uses?

A few people really prefer how OS/2 works to more modern solutions. Some enterprises have big investments in OS/2 programs that have no equivalent on other operating systems, and which are difficult to port. For many users, it would be expensive or inconvenient to move years or decades of their data and programs to a new platform.

For some users, having something different that works is a good enough reason.
