My main OS/2 machine has evolved since the mid 90's, it just works and I'm happy with that. The few problems I've had have been of my own making in doing things I probably shouldn't be doing under the hood, or due to hardware failure.
OS/2 allows me to get my work done, and I cant help but notice a lot of people that use other operating systems seem to spend an incredible amount of time updating, restoring, asking for help, mixed with weird and strange things happening after updates. I don't have time to spend fixing base operating system problems.
I do have AN installed on a laptop for traveling, which is about once a year, I do mean to try using it more but my current OS is still comfortable, and working, since the mid 90's..
