Pre-Windows 8 apps won't fit into the new Windows 8 model without being rewritten for new APIs/style. If we assume Windows compatibility is then no longer what drives Os marketshare for PCs (a big leap, but one Microsoft seems to be making), then this would be the perfect time for Android or WebOS to make the bid for the desktop and business users. Obviously OS X is limited by being Apple-devices only, so where is the next big x86 compatible OS that desktop manufacturers will sublicense? On the interface, I absolutely think Microsoft can have Metro UI conventions and complex applications without compromise, but it seems ill thought-out to believe you can scale a phone interface up without greatly increasing the density of information or ability to interact with data, of which the preview seemed devoid. The "wall-mount problem". What looks great on a wall-mounted monitor is not the best interface for my actual desktop computer.
