music to my ears as a free software zealot. microsoft is going off to build an os "done right"...where have we heard that before??
wait for the concessions and half-baked reversals. they're obsessing with a whole new kernel, that will likely be the first decision to get dumped as they watch MSFT drift down to 18 with no new product on deck to rally sales.
then having ditched the "rewrite" plan, they will spend a year spinning their wheels trying to locate the best two or three ideas from midori to graft on to vista, people might just jump to mobile platforms full-time, or the console market might start seriously eating into pc sales, or everyday people start using ubuntu, etc etc etc.
the market just isn't going to stand still for five years while microsoft tries to relearn how to build big systems. microsoft is chasing google, they are chasing apple, they are chasing oracle, they are chasing nintendo, they are chasing linux....
its going to be fun watching this company feign relevance while going the way of DEC
