I'm aware of many of the things ARM is used for.  Yes, they are quite 
useful.

But, are they much better for desktop and notebook PCs?  I really can't 
see them being much better in that environment.

Now, talking Microsoft, how successful have they been outside the 
desktop and notebook PCs?  Not very.  So, for them, x86 does the job.

I have no idea of cost to get a decent WEENDOZE on ARM.  But whatever it 
is, would doing so be of adequate benefit to Microsoft?  Maybe sometime, 
but right now I don't see it.

Then again, I don't get out much ....
