Square (squareup?) is super badass.

Looks like Square went public today. Hot. Its a device and service that lets you take payments from any credit card anywhere via iPhone.

Rumor has it that the device (that hooks into the iPhone audio jack) should be super cheap too.

I think they have the potential to totally change personal payments. Isn't this what PayPal was supposed to be originally?

FINALLY someone will solve that dreaded "How do we split the bill?" issue. I can't wait to get one.
