Blasphemy - I cannot, for the life of me, conceive how one thinks the world should proceed without desktops. I thought you were going to suggest they open up MacOS so that it can run on Windows or Linux but instead it seems you're suggesting they abandon the whole OS. It would be courageous to abandon desktops and open up the OS - it would be foolish to abandon it altogether. The moment Apple abandons desktops or the OS my iPhone will be silenced.
I think abandoning the desktop is a really bad idea, I'm simply suggesting that's where Apple may be headed. Management doesn't show much interest in desktop Macs unless forced to, and if the focus is on fashion and ROI for investors they might be looking for a route to get rid of what they seem to view as an annoying side business.
