What about work?
All well and good for lounging, or entertainment. But what about work? Cut and paste across database forms, schedules and publishing a patient schedule letter for cancer treatment, or monitoring instructions, plus stock reports, plus order entries and acceptances can become daunting tasks -- these data intensive operations still do not seem to fit on Windows 8 with it's "full screen" pretty graphics. Looks like business is being left behind -- Microsofts most solid, and least fickle income stream.
I think there really needs to be a split between business apps and entertainment, with bridges between the two, rather than integration across everything.
