thanks for the links john a.
personally i think mikrosovt will only succeed with computer brands who want to be solely sold with that specific os.
not every computer manufacturer will meet the demands of just one company, take a look at the server market: how many servers run a penguin?
there's also legislation in different parts of the world, like in the eu as you already pointed out.
so in the end, they maybe even have to launch their own hardware brand to make this work, just like them apples.
compare it to a car: like the looks of a brand but want to buy it with an engine from another brand; you can' t (therefore: buy only volvo's build till 1995
p.s. good thing to notify a consumers organization on this newest 'idea' from the redmond moloch.
