For my headless Pis, I attach a BT TTL serial port to the rx/tx pins. They run about $15 or less. This lets me pair to the serial port from my laptop, watch it boot the kernel, login and do whatever cli commands I need. I can also use BlueTerm on my android phone to do the same thing (though make sure you get the hacker keyboard if you go this route).

Here's pretty much the article I followed, though I bumped my console up to 115200. http://blog.miguelgrinberg.com/post/a-cheap-bluetooth-serial...
