Now that Android on the n900 looks more possible than ever, I'm just curious what you guys think an ideal button map would be. It would be great if we could have the home, menu, and back button functional when in portrait (closed) mode. I would love to keep the volume rocker dedicated to that, so that would leave the power button, camera button, (maybe) proximity sensor, and (maybe) the power switch. What if we could use the camera button like it is with camerad... so when the camera was closed it could be a two way switch: click it half way and it would be menu and all the way in would be back? Then the power button could be home. Thoughts?
