This is exactly the kind of FUD that is slowing Linux development and 
preventing wider use. Windows, for all its faults is a VERY BIG commercial 
success. You (and I) may believe that MS have persued some pretty bad 
practises to get where they are but the FACT is they are there and YOU are 
here.  You may (I don't) believe that Windows is inherently unstable. This is 
FUD. It mostly works, sometimes it doesn't, but in total the number of 
working hours of PRODUCTIVE use from it is many orders of magnitude greater. 
Multiple the number of Windows users in the world by their working time and 
then do the same for Linux! 

I have not proposed a driver model that is compatible with the Windows DDK. 
This is pure invention from the usual school of 'Windows v Linux, Linux is 
better because we made it'. The Linux driver model could be much better and 
hence the OS could escape the niche box it currently is in. Please ask Joe 
User how he feels about rebuilding his whole OS to add IP6 support to an 
existing stable system etc.

You have accused me of not knowing anything about OS design. I don't what your 
knowledge is, so I won't try and score points by telling you about mine - 
what I do know is that you obviously don't appreciate what is holding Linux 
back - You.
