First, the very last impression that any company wants to give investors, financial analysts and the financial media is that a company can only do a handful of things well, and that the company is too overly dependent on any one of its product lines.

I think this is a problem. It drives businesses towards becoming large, overly-diverse corporations that tend to do nothing well. Sure, some companies—like Apple—manage to avoid it. Many more, however, become Hasbro.
