I have a Nexus 7 with a bluetooth keyboard, I rooted it and installed Debian. I can SSH into it and pretty much do anything I want (I use ConnectBot or Terminal IDE). I have installed Vim, PHP5 Cli, MySQL and also PHPUnit. For testing sites locally in a browser, I have installed KSWeb. I also use an RDP client to access the LXDE desktop on Debian. Is there really a need to SSH into an RPi when one can have a setup like this?
