almost all windows since 95, a lot of mac OS since 7.5.3, OS2, a lot of linux, OS9000, solaris, AIX and *BSD.
My experience recently has been that all OS are having problems. Just to name a few :
- HW vendors doing sub par drivers and documentations, and integration :you even have more than one HW for the same model;
- ACPI
- forced obsolescence of peripherals;
- outsourcing is clearly related to loss in quality especially in HW;
- too much packages and dependencies;
And still : most developers don't know how to do asynchronuous programming, and that is really a problem when everything is about handling events.
