Adam Lisagor, he runs a company that produces these concept videos: http://sandwichvideo.com/

I'm surprised that he also stars in them. That seems like it would make things more complicated to shoot (but maybe cheaper and easier to produce.)

I think the product seems a bit dangerous and I'm not interested in buying it, but I thought he played it all perfectly. I especially liked the bit where his mum called.

But it looks bulky and the display is a bit low and meagre. I don't think we should be encouraging people to read/compose tweets or texts while driving. Take a call or get directions or show my speed and the limits, sure, but tweets can surely wait.
