Re: Still not enough
Do they? Most regular Windows users (i.e. non-techies) don't really seem to like the classic start menu... nested menus are fiddly and you can never find anything. That's WHY so many Windows PCs end up with the desktop totally full of icons... which is not dissimilar from the W8 start screen.
I've yet to see anyone explain why a full-screen start screen is a bad idea, only to keep reiterating that is. When the start-menu is in use, you cannot use another application, the UI is fully modal. So making full use of the screen rather than force you to look in one corner while the rest of the screen is unused isn't really a bad thing.
You only have to look at OSX, regarded as easy to use, to see this is not some controversial new design. On OSX both the Applications and Launch-Pad thing open a big tiled window. Granted it's not full-screen but it's far more similar to Start Screen than Start Menu.
The Metro UI is clunky on a desktop, for sure, but that is now optional.
