It has wi-fi?
1. to install skype or sip tonelico and use as a phone.
2. if there is a webcam above the door in the hallway, then attach the PDA to the wall (to bring food) and open a browser with the image from the camera.
Both versions have long plagued me, but not going to try.
If there is no wifi, then give it to someone, and wishing already have! :)
