I'm thinking 20-24", probably wall-mounted to replace the whiteboard we've put up now. Preference would be a touch screen. I'm fairly tech savy (assemble my own desktop PC's)...but remain on Win7. Mom is in another state, so need something that is on 24-7, that I can easily and remotely enter new display information on...like caregiver coming at 10:30...Doctor appointment at 2:00, a picture, etc and perhaps can be used for her to skype.
