Cable secure an iPad to a table/desk
I would like to put an iPad in our office reception for people to play with when waiting. I need some sort of security cable to tether the iPad to the desk. Ideally I'd like to keep the iPad itself free from some overwhelming case that covers the device, so the options I have:
One of the retractable wire with some sort of electronic alarm would be good, if a little annoying as the cable want's to retract all the time. Much like what they use to tether them down at the Apple store. Does anyone know where I could get one of these?
A heavy duty wire that attaches to the iPad, somehow. Possible on the USB dock and then it doubles as a charger? Like the Targus one available for ipod? Would it work with an iPad?
I've done an extensive search on google and come up with no suitable products. What do you think of the above and are there any solutions i've missed out there?
