The problem with Forstall is that he's not mature enough yet. I don't mean that he is childish or impulsive (which he is, but that's not necessarily a bad thing). I mean that he hasn't yet developed that innate sense that one needs to be a great CEO. Much like the ability to appreciate art or fine wine only comes with experience, he needs more time to develop his talents before being given command of a ship as big as Microsoft. I think the whole "maps apology" incident demonstrated that, and this is why he's no longer with Apple. Remember, even Jobs needed two sizable failures under his belt before he became the Jobs that we all know and remember.
