I gotta say that I love my 810. I am constantly finding new uses for it. I am currently doing sat installs and it is my assistant. Since I use the 810 I have not had a charge back for missed appointments. Your supposed to call in and describe the building or something that stands out, but customers tend to complain that the tech could do that anytime. Well a timestamped and geo-tagged pic works well. Same thing for disputes. I set up a file for every customer and take pics of the installs. No way to argue that. It keeps track of all my appointments and syncs to google calendars. I take notes during meetings, perhaps a sound bite. Great for keeping my tech docs. Gps takes me to the next appointment. If I have down time I can listen to music or watch a movie, if there is wifi I can watch foreign channels. I have also used log me in to help my moms with issues on her machine. Sorry for the jumble, but I tend to get excited about my useful gadgets.
