@asmodeus, @twobikes: you will likely not find a Nexus 7 in retail in any major US city. Smaller towns are fine, but the only way to get your hands on them quickly (3-5 days) is via Google. If you're somewhere far out of town, try Staples (their online store has an inventory finder).
New Zealand is the first place I've seen N7 actually in stock. $130 NZD premium over USD pricing seems a bit steep, these things should sell for NZD $299.- + GST. That's our retailers for you.
