Unfortunately, some win programs can't execute as anything but
administrator. I've tried to set the user accounts on my kids' windows
machine to something other than administrator, but 1 out of 3 programs
they use on a daily basis seem to fail. Sadly, it appears that application
writers assume they can have their evil way with c:\windows.

Regarding linux, you sure that the code is not some pseudocode? I know
these files can do things like access the internet.... perhaps they can
select which bits of nasty goo they download. If so, it might be possible
to have them determine the OS first. Sure was nice when you didn't need
armor plating on your computer.

That is what Apple did (more or less) for OSX. By all accounts, it is
great to use. Sadly, they still are too stupid to a) figure out that their
stuff is better than windows, b) port it to intel, and c) price it in a
predatory way to eat Windows' market share. They are afraid of retribution
from the Word/Excel team, I'm guessing. I can't think of any other reason
why they wouldn't do this.

Slacker. I like Fedora Core 4, which appears to work, and has pretty much
everything you want available.

Wine keeps me going most of the time (hiccup!). Unfortunately, it doesn't
like graphics intensive games or the flying model simulator, so I have to
boot into windows for my fix of flying and pseudo-death. Also, sadly, the
Zilog C compiler doesn't run under wine. MPASM also fails, but I've got
linux tools for both d*** and the midrange series.
