Jerry, there are so many things that are so wrong and so un-pc in this 
statement that it is more than ridiculous. But we will ignore the 
political/religious sentiments and try to stick to the technical.

Winblows, Mac, Linux, BSD, others APIs are like cheese and chalk 
(although Mac is a closer relative than any other). By your logic we 
should be getting Winblows drivers to work on BSD.

And thats not even touching the licensing issues. Or the simple design 
policies (such as userspace or kernel modules) that differ from platform 
to platform.

Some ray of hope allowed some linux drivers to reach the horizon, but so 
far only usb is remotely possible.

Perhaps you might become enlightened enough to do the research (like I 
did) on the background and core details of what is involved before you 
start a rant such as this. This has been brought to your attention 
before, only recently in fact.

Start with an introduction to OS design textbook and you may just barely 
touch the tip of the iceberg...

And if you see us as people floating in the ocean after a ship sank, why 
are you still here then?
