I see that you chose to ignore the rest of my mail, which got lost on the way 
to the lkml apparently because it was infected with some HTML:

----
Windows 9 will have no support for Aplha, m68k, risc, PowerPC, SPARC, ESA/390 
to name a few.

They could be dropped as well, but why?
----

You could call these architectures deprecated as well. However I like the fact 
that Linux doesn't try to force the users into using some specific hardware 
(or software for that matter), as some companies tend to do.

BTW: This mail is written on an asus eeepc (32-bit intel thing), and my first 
hands-on experience with Linux was on an amiga 1200 (mc68030). Naturally, I 
love the versatility of Linux and see no reason for dropping support for old 
hardware unless, it is _really_ not used anymore (token ring comes to mind).
