Some time ago, we ran a poll.  At the time, the EVO 4G had just landed in retail stores, and I wanted to know how video calling affected your life on a daily basis.  Since then, the iPhone 4 has launched, and despite some initial issues, the ability to video chat is now in the hands of 3,000,000+ Americans.  So in light of Noah's question today, it's worth asking again.  With the availability of devices like iPhone 4 and the HTC EVO (and more on the way), do you use your smartphone for video calling?  Vote and defend it in the comments!
