This is precisely where I think MS failed miserably with Windows Phone. They had an incredible opportunity: Make a smart phone that is a full, natural, joined-at-the-hip extension of your desktop.
They did not. Instead, they made a separate device. This was, from the perspective of desktop integration, 100% indistinguishable from any of the other offerings out there. They were playing "We too" when they should have been playing "Check this out!".
Something as conceptually simple as a docking station that instantly brings your phone into your desktop as a first class integrated app, able to interact with other applications, including browsers, would have been a huge step forward and a massive selling point for Windows Phone. Add to that an open API for developers to be able to integrate desktop Windows Phone services into their applications and MS would have had the makings of an ecosystem that would have just exploded into the business community in a massive way.
Instead they wasted time and money with an offering that did exactly the same things as any other offering while trying to invent a new UI. The strategy was doomed to fail before the first phone was introduced. They tried to build an iPhone with a different UI when the business world would have energetically adopted a deeply integrated extension to desktops in the form of a smart phone.
To this day, I still think I would drop iPhone in a second if MS came out with a well thought out system along the lines I described above. The paradigm shift (or the twist in thinking) is that the phone is given life as an extension to the desktop experience rather than as an afterthought that behaves as a peripheral. It would be like a sci-fi movie where the person grabs an application from the screen, it materializes as a physical device in their hand and they walk away. When they get to the office they push it into their display and it melds into that system instantly. Sci-fi aside, that feeling and utility would be incredibly useful.
