I do not agree with you. I'm using OS2 for over 25 years, and I can assure you with OS2've saved my money to small business.
We recently added some Windows computers, and windows, there are other problems. You have to change teams often fall because of insufficient performance, some programs stop working from one version to another. Other programs win, bitches are updated annually shows that if we pay them, the system slows to a stop.
For me the main problem is the lack of applications OS2. You can have the best system in the world, but if you do'n have applications you can do with it.?
Formerly it was said that the future was java, today is a java seen that this is a disaster. With new versions almost every day, impossible to have them updated on all systems.
Perhaps the future passes through Q4, or the portability of the Linux world. This time will tell.
But for me the great success of the OS2 to the REXX been. The programs are based on REXX, have the advantage that each program is not entirely independent, you can do with a few lines of rexx, talk to each other, to understand each other and do things together as if they were a single Super App. Dbexpert, Mesa, Truespectra.
