It isn't great that Telstra customers have to wait for their operator to approve WP7 updates. Of course, this still sounds better than the Android model (where many customers can never get upgrades for their phones).This is a case where Apple has a clearly superior and more user-friendly model.

However, aside from that, the post just seems to have a laundry list of minor complaints about the marketplace. Some of these problems have existed on itunesconnect as well. (For instance, on one occasion, I had to use Firefox for a part of the app submission, because Safari couldn't do the job)

I'm surprised that these issues are the cause of his regret. (Note: I say this an iOS developer, who considered WP7, but decided against it).
