Marco Arment wondering about the same hurdle that I foresee Microsoft having with Windows 8 and Metro:

The question isn’t whether Metro will be good: it probably will be. And that’s a huge accomplishment for Microsoft that they should be commended for.

But how will their customers react?

The fear I have is that Microsoft will have created this great thing that is shunned by their core user base, thus allowing the “I told you so” crowd to take back over at the company. The fact that Metro got past that crowd already is nothing short of a miracle.
