That's why the android emulator, even though it is so so so SO slow, proves a worthy tool to develop with. If your app runs quickly, relatively speaking, on the emulator, you've got a good app.
There is slow and then there is unusable. The emulator is the later. If it had any decent performance it would run at the speed of the slowest android device available, but it doesn't even do that.
Using the emulator you're conditioned to the slowness. You can't even set a valid baseline. Now your application is so slow you can't tell if the performance is due to the application or the emulator.
