I tried an iPad at Best Buy the day they came out and could not load Google Maps. I figured it was the Best Buy LAN but then the reports started. Bought a 3G and 20' from an Apple Airport Extreme, with the iPad sitting still on a bed the signal will go from 5 to 1 to 3 to 1 bar in a minutes time. After doing that a few times it stays on one bar and I am unable to use any internet. The 3G does not kick in because I have 1 bar. 3 Macs, 3 iPhones, and 1 iPod all have no issues. I took it back to the Apple Store and they swapped it saying they had heard of the issue but had few returns. The second one does the same thing and now has a hot pixel too. What I did notice was that if I go to the other side of the house, where I have an Airport Express extending the main WiFi, is that once it hands off to the Express it seems to keep 5 bars. The issues appear only when connected to the Extreme.
