That is basically what Apple did with the iPhone. There were lots of apps for the other mobile platforms at the time, but the iPhone was simply in a different class. The problem is that today, you have to come up with something that much better than the iPhone. If a Nokia phone and an iPhone are of comparable quality (which I think has yet to happen), but the iPhone also offers you access to a huge variety of apps, then why would you get the Nokia? It needs to be significantly better in some way.
