Android emulator there are still many benefits, but in terms of operational efficiency is not very realistic simulation, simulator, or by PC configuration of the computer, such as the CPU to handle compressed files in the PC side of L2 cache and large capacity becomes ARM processor weak, but the android emulator is still a lot of benefits.
Kml file test using the gps is very convenient, no need to go outside to search for satellite signals, as the powers with relatively large, you can visit / data / data files, and this is not normal in the real machine Root permissions are not accessible, simulator Dev Tools tools for unit testing the efficiency of the software useful, API Demos is also a real machine does not pre-installed, so if you buy a G1 may wish to buy a Android Dev Phone 1 or better using the simulator.
