Come on product managers! When I'm running between terminals in Heathrow, Beijing, or Atlanta and all I want to do is look at my calendar to confirm a flight number I don't have time to click outlook have my email pop up then click the calendar.... Even better I want to leave all three distinct apps running in separate windows in the background and simply jump to the one I need. I get it; some fresh MBA trying to make a name fudged together a faulty / unproveable / unaccountable business case and convinced management that putting them into one MEGA App will promote the Office "eco" system.
