I've worked with one large corporation (30K employees). This corporation went from HTC WM6 to HTC Android phones, with an option that employees could buy their own iPhone / iPad and use it on the condition that it is set up by the IT staff with proper security settings. From what I can see they have a lot of iPhones and iPads there. People considering an iPod Touch might think twice if the company allows an iPhone. I agree that they need to narrow their focus, but I don't see how they can differentiate in the enterprise market in a way that will make them own that market.
