99.9999% of applications for Windows are not going to look like Metro apps including flagship products like MS Office. So Metro is going to get in the way most of the time.
I'm not sure what desktop users should really appreciate about Windows 8.
This makes me laugh. It was not long ago, not long ago at all, everybody was complaining about how old-fashioned and unresponsive Microsoft was being.
I have primarily been a Mac user for the last couple of years (whenever I have a choice about it), but I'd love to see MS start making its self more relevant again. I feel the consumers (i.e. my) interestes are best served when progress from the tech giants are spurred on by their competition. Not when a single platform has the majority of mind share in terms of perceived innovation.
Apps.
