This may be the end of Windows Mobile.

It will either fly or fail. There's no in-between.

At the moment, Windows Mobile is failing. But some hang onto the thought that Microsoft's next mobile OS will be better and fix everything.

But what if Microsoft's next mobile OS merely catches up to the interface achievements of iPhone and Android? That won't be enough. Microsoft must do better to dislodge them.

If Microsoft's next mobile OS is a nice OS, but nothing special, we will then know that is the end. There is no hope beyond that.

Well, that is, unless Microsoft goes to Plan C, and buys out RIM.
