Oh come on, when was the last time you even picked up a real brick? Are you people so weak and your hands so small from never doing any physical labor that a phone measured in ounces is a challenge for you to hold?
The "big round brick" comment was meant as a joke... just a bit of sarcasm! And the joke wasn't meant to reference weight as much as the warped aesthetics of the phone with the giant battery attached.
On a side note... The last time I picked up a brick was just about a month ago, but the brick wasn't nearly as heavy as the pile of roofing tile that I hauled up the ladder before that.
