-
- OS/2 does use priorities (and dynamically adjusts them depending on
- various factors, although that behavior can be disabled). As shipped,
- OS/2 does not include a utility to adjust the priority levels of
- running tasks (or tasks you start); however, many applications include
- this feature (especially communications programs) internally, and
- there are at least a couple utilities available via anonymous ftp from
- ftp-os2.nmsu.edu which will let you adjust program priorities (NICE
- and SETPRI come to mind).
-
- IBM evidently decided that this utility should not be included in the
- base operating system since the company wanted to avoid adding
- complexity, but, if you are a savvier user than most, the utilities
- are out there for you.

-
- Indeed.
-
- The short answer is, "Because we're not there yet." (Unix is very
- similar to OS/2 in this respect.) But there are probably some good
- technical arguments why device drivers, in the main, are loaded in
- CONFIG.SYS, at boot time. I'll leave that to others, but I have a few
- in mind.

-
- Mostly. In OS/2 System -> System Setup -> Mouse you have several
- speed adjustment options. Some people aren't entirely satisfied with
- the range of available settings, but feel free to experiment with
- them.

-
- I know it is being worked on, but part of the problem is that, in
- order to maintain backward compatibility, those 80x25 windows are
- extremely important. If you start to get too fancy you then start to
- break things.
-
- It is certainly possible, but it is moderately difficult to implement,
- and my hunch is that the designers of OS/2 focused their energies
- elsewhere first. While a "Cadillac" command line window would have
- been a nice feature, they settled for a Chevy there and gave us a
- Cadillac GUI shell.

-
- Oh, always. OS/2 will continue to evolve at a rapid pace.
