Technically, if you bind a hotkey to "killall -USR1 configbutton", you should be able to open it with your keyboard.Yeah, I usually take screen film off quite quickly, but any other film protecting shiny plastic I leave on until it gets really quite grotty. I don't really like shiny plastic, so while the film looks no worse than it would look being off, I'm not fussed.
In terms of not using the touchscreen, my forced TV-out only unit doesn't have one, so I'm quite used to keyboard shortcuts and the likes. The only thing I absolutely have to use the nubs for is to get the system menu up (the one containing CPU speed, and options to turn on/off wifi, USB host, bluetooth etc.). Yesterday, my right nub decided it was going to turn off (or otherwise not report any value but [0,0]) so I finally had to figure out how to do all of that stuff using the /usr/pandora scripts. Turns out setting the cpu speed is surprisingly easy; '$ sudo /usr/pandora/scripts op_cpuspeed.sh 600' sets it to 600MHz. It's probably got the special privileges meaning I can run it with 'sudo -n' and not even have to enter a user password, thinking of it.
