I see opportunity here for someone to make a "Business OS." Microsoft has forgotten who pays their bills. Business users do not want all this crap.
Not really -- employees are consumers too, and the lines have blurred somewhat. That has definitely been a recurring theme throughout D9, starting with Eric Schmidt's line that traditional IT is dead.
Consumer != powerless.
Touch-first OS with Excel? I'd like to see that done right.
Even something as simple as a time management system may take several years and tons of money to transition from decade-old WinForms app to new web app.
