I'm not sure I know of a better mail client being denied from the app store. There are many better browsers available though.

I concur with the theory, but the reality is that the other platforms don't have a meaningful number of customers nor any significant momentum in the app sales channel. It might make sense to port something if it's easy, but I'm not sure I'd be willing to invest time unless it was under contract. Apparently a lot of other people must feel the same way judging by what's out there now.

We still need to hear a lot more from MS on their strategy in this space. I just read something the other day that mentioned they'd be in a position similar to Apple in 2007 where only approved, high-level "partners" would be writing native apps for the new Windows Phone. Anyone else have any concrete news on this subject?
