AirPlay Everywhere

This is huge, and it's likely that Apple will enable this for themselves in an iOS update at some point.  I can't count how many times I've browsed video on my laptop with others around only to wish I could throw it onto my TV.

The more I think about it, could we have a future where TVs don't have inputs?  They would be simple streaming clients to which other devices push content.  You've got your phone with you - why would you need anything else?
