Let me get this out of the way first: the Nexus 7 is not a smartphone, nor is it a tablet designed for incoming / outgoing calls like the original Galaxy Tab from Samsung. The Nexus 7 is a very basic tablet that is meant for doing tasks like surfing the web, socializing on Facebook, Twitter, sending / receiving email, play games, video chat via Skype or Google Talk etc. i.e. nothing to do with phone calls.
