I have both an iPhone and an Android with dozens of apps on them.

But I could do without all of them, all I need is an Email client + a browser + a Skype client.

If you build a usable/reliable OS with a usable browser and email client, people will buy your phone and devs will come.

WP7 is not even on the radar yet for developers. Porting apps to WP7 for me is waisted effort instead of improving the code-bases for Android / iOS (which also have shared logic that I cannot port easily to WP7 because WP7 doesn't allow native code).

Right, but the problem is MeeGo doesn't even exist in a final or mature form yet. As Elop said, they could probably only get a MeeGo device out next year!

As for the native code argument, well I don't entirely buy that. Developing for WP7 is easy and accessible enough - as evidenced by the flood of apps the platform has already.
