It is clear what the "masses" want.
The fact is that the majority of the winning concerning the Metro issue is done by Enthusiasts (the One %) and Not by Business.
Business and Enthusiasts will find their solutions (that is what they are good at).
And why can't Microsoft have multiple product lines?
Look at the car industry. Ford will sell an F-350 to contractors who need to carry 4000 lbs of bricks. They'll sell a Fiesta to the urban commuter. Etc. No one is putting a pickup box on a Fiesta chassis and telling contractors that that's their new truck and that they should "find their solutions".
Make a "Windows for content consumption" and a "Windows for productivity". Sell the former on tablets and $400 AMD E-450 laptops. Sell the latter on desktops, laptops with decent resolution screens, and volume licensing.
Really, they're halfway there with the no-Win32-API Windows RT on ARM. That thing will not have productivity software for years and years, if the Autodesks and Adobes of the world ever even port to Metro. But for some reason, they had to compromise the x86 version.
And finally, I hate to point out the obvious, but what the masses seem to want is the iPad (and iPhone). A device with an extremely intuitive OS, an installed base of 80M units, beautiful styling, no third-party "partners" mucking it up with crapware, and a vibrant third-party ecosystem with tens/hundreds of thousands of apps. Every other tablet has been a flop so far (and understandably - I had one of the $99 HP Touchpads, and the software on this thing was buggy s**t that should have had a beta label). What makes anyone think that this monstrosity, with a less intuitive interface, hardware of unknown quality/fashion/etc (but probably higher price given Apple's economies of scale), <50 third-party apps, is going to be well-received by the masses even as a tablet platform?
