Like I said, it depends how blurry your spectacles are. You wouldn't class a PC motherboard as a development board would you? I don't see that as being any different to the pi.

Could average joe technophobe do anything with an arduino in 10 minutes? No.

Could same average joe technophobe have his raspberry pi connected up to his tv, running xmbc and playing media in 10 minutes? Yes.

I personally think they'd have a very hard time trying to convince the relevant authoritative bodies that it was only a development board in the case of a problem with emissions.

The sales numbers that are floating around 100k+ and the interest in the media playing says to me that a lot of these units will sit behind a tv and have certainly not been bought by people interested or capable of software development.
