Some of these I think are valid points, the update process needs to be improved. Currently it feels like the WP7 update process sits somewhere between iOS and Android, all the problems of both and the benefits of none. Smaller updates released more regularly would go a long way to solve these issues.

The marketplace update process I've never had a problem and I've used both Firefox and Chrome never IE. I'd love to hear some of the marketplace rules that he feels are broken. Most to me seem pretty up front.
