But where is the Mac Touch hardware ? you could see for a while where touch was it and we have these nice laptops and big iMac displays but we will use a mouse ?! I really want my next imac to be a docking station with a tear away tablet
Windows 8 is definately banking having this sort of hardware in laptops and displays being available. You dont do Metro on the desktop unless you think that kind of hardware will be available in some form at launch. Metro with a mouse is hideous, even for Microsoft...
You'd have to either make your operating system work very well with both touch and mouse/trackpad/keyboard (very difficult), treat touch as a gimmick (as with those Windows 7 HP iMac-like things with touch screens), or make touch (which is ergonomically highly problematic on anything but a smallish tablet) the first-class citizen.
I don't think the technology exists to make large tablets ergonomically feasible. In order for the tablet portion to be light enough to casually pick up and carry around, it would have to be not much larger than an iPad, which is to say, less than half the smallest reasonable screen size for a desktop.
