I also heard the rumor with one additional detail. Before agreeing to make a bid, Dubai's monarch called up Jon Ive. The monarch asked Sir Jonathan to make iOS7 icons more Islamo-friendly (flat, austere, less illusionistic). You see, in Islamic culture, renderings of people and animals and illusionistic depictions of all kinds are often مكره (makrūh) (disliked) and sometimes حرام (ḥaram) (forbidden). Could this be the reason for the new flat-as-pancake iOS7 icons? If you agree, please click the thumb's up icon, which means ب (mustaḥabb) (recommended).
525 billion is too cheap of a valuation. Company is worth atleast $620 per share (fair value)....this translates to 580 billion market cap. Since they instituted the buyback $60 billion, the company should be worth $680 per share fair value.
