I think you missed the mark on Squirrel, completely. This is, to me, one of those things that you can show people and they'll think this is why I have a computer or cell phone.
There is only one bank (USAA, http://www.nytimes.com/2009/08/10/technology/10check.html?_r...) that accepts photographed checks on the iPhone. Besides, I don't know anyone that carries checks around, whereas almost everyone I know carries a credit card and some (usually small) amount of cash around. The cash usually doesn't break up easily. Whereas with credit, you can bill the exact amount necessary. Only, its pretty difficult for people to accept credit cards from a friend.
Squirrel changes this. It's person to person, peer to peer payment. You can go out to dinner with someone and split the check, exactly and not have to deal with "Do I owe you $10 from last weeks dinner? Didn't I buy you a few beers last night?". You can have a garage sale or a stand at a market somewhere and accept payments right there in more forms then cash. This is likely to be far more convenient to use then a check is.
