I personally do not think WP7 in its current form will ever be a success. Ecosystems count only to people that have vested interests and usage of that platform. And face it, Windows share has been in steady fall for the last 5 years. So that means less people today are using Windows than they were during the Windows Mobile 6.x days.

Nokia picked the slowest horse out of the bunch out of the gate. They dismissed MeeGo as an incomplete operating system, but Elop was overlooking that WP7 in its current form is an incompete, restart of an operating system as well.

What will happen when WP7 fails to achieve expectations? Microsoft will throw more money at it.
