Development PC

The emulator is pretty slow in general. And if you're running the emulator plus Eclipse, plus a web browser, you're using a lot of ram and could start swapping out to disk which will make things unbearable.

So if you want to use the emulator and have two computers it might be worthwhile to use it on the second computer. Another option is to do most of your testing directly on your phone(s). I use the emulator as a final verification for any setup I can't test on real hardware, but most of my testing is done on a phone.

 

I just have two computers on my desk because I like having multiple monitors. I share the keyboard and mouse with Synergy.
If you're using Linux you could instead do X11 forwarding. If you're using another platform you could use VNC.
