I think it's bad there, too, but it's maybe a slightly different situation: iOS has never pretended to be anything other than a very locked-down walled garden; Windows is supposed to add bit more flexibility. If iOS actually allows other browsers to be installed, then it's made some kind of 'progress', but Windows is moving in the other direction: there's a pretty undesirable average that they both seem to be heading for whereby you can install alternative applications, but the OS will make it much harder for you if you do.
