Trying a one solution fits all approach was always Microsoft's approach. Back over a decade ago when I was big into MFC development, it was amazing how much of the Windows bloat was present in WINCE (or Windows Moble as they later styled it). It's almost impossible to differentiate a desktop and mobile on the Windows side. They tout it as an advantage. Oddly, Android gives an indication of how to do it right. Sure, you can take the essentials out of the common system, but you don't have to move inappropriate bloat over.
