Could Microsoft go the route of Blackberry and make first party Android devices? Similar to what they did with the "Microsoft edition" of the Samsung Galaxy a while back, but take it further and sell them as exclusively "Microsoft" branded devices. Whether they resurrected some of the Lumia pipeline to run Android or designed their own or licensed unique designs from a hardware manufacturer like Blackberry did would all be possibilities. That would seem to make the most sense at this point if they want to craft the experience for enterprise. Obviously they failed epically with W10M, but leaving businesses and consumers to their own choices (by just offering up apps for people do download) seems to be leaving their fate too much up to individual choices, and perhaps they will suffer a death by 1000 cuts (again) as users continue to passively shy away from their services.
