Från Wikipedias artikel om OS/2:

The difficulties in efficiently running OS/2 have, at least once, created an opportunity for a new virtualization company. A large German bank needed a way to use OS/2 on newer hardware that OS/2 did not support. As virtualization software is an easy way around this, the company desired to run OS/2 under a hypervisor. Once it was determined that VMware was not a possibility, it hired a group of Russian software developers to write a host-based hypervisor that would officially support OS/2. Thus, the Parallels, Inc. company and their Parallels Workstation was born.

Jag använde OS/2 under flera år. IBM tappade verkligen en stor chans där när de bestämde sig för att gå i rak kollisionskurs mot Microsofts Windows NT, och samtidigt inte göra varken operativsystemet eller marknadsföringen på ett tillräckligt bra sätt
