I was actually referring to the webOS emulator:
"Currently, the emulator does not support the following:
* Bluetooth (UI and any interface-specific APIs do not work in the emulator)
* Gesture area
* Wi-Fi (UI and any interface-specific APIs do not work in the emulator,
but network connectivity works by using the desktop connection)"
If the emulator supported multi-touch and rotation, I think this would work
well for testing any mobile web content where the developer is concerned
about memory and processor limitations. I think a lot of physical devices
can work well as a canary in the coal mine, though. If I weren't messing
with maps so much, it probably wouldn't be a big problem.
