Every time I see stuff like this it makes me slightly glad they got laughed out of the smart phone game. Can you imagine if a Microsoft mobile OS became a serious third between Android and iOS? I mean, those two aren’t great by any stretch of the imagination (and are probably doing or planning similar shit), but Microsoft is just going gloves off at this point.
