"...it took over a decade to only move 80%..."
Ah, the old tired adage, or should I say FUD, used by all the MS shill/Fanbois/Wintards.
Of course it took time you moron. They first had to consolidate all their disparate IT camps that were using a Wintel environment and then move forward with a migration. Gov is about as maneuverable as an aircraft carrier. It takes time to turn.
As for the real world, most of it is locked into Microsofts crack, er, licensing.
