@kettch: Belfiore makes it pretty clear they think of convertibles as "laptop which occasionally get used as tablets" and from that point of view, many of the kludges that come along with the Windows desktop environment are passable. If you expect to mostly work on the desktop, then you probably overlook how the experience works the other way around ie as a "tablet that occasionally becomes a laptop"
So things like the tray notification area being full of finger unfriendly icons is a pain. Metro apps appearing and permanently remaining on the taskbar is a pain - seriously turn that option on in Windows 8.1, run through using 30/40 tablet apps as a tablet user would and then switch back to the desktop and try to clean up the mess - and a million and one other little points have reverted to the idea that it "works OK" for touch if you just slightly resize buttons even though this demonstrably didn't work in Windows 7.
And the thing is, Desktop users should be the ones complaining about this more than anything, because if you can't get the convertible scenario to work you might as well abandon the entire concept and have a tablet edition that is entirely separate from the desktop/laptop version, which would allow you to avoid having to restrict the desktop at times to accommodate these devices.
