NBA point guard Deron Williams just signed a $100 million contract with the Brooklyn Nets — with his finger.

That’s because he did it on an iPad. Gone are the days of obscenely thick paper contracts. Everything’s digital, touch sensitive and tactile now.

Officially a Brooklyn Net! Signed my contract on an iPad Just thank God for this wonderful Opportunity

We’ve already seen how the iPad’s transforming the way we conduct businesses. But this just elevated the stakes.
