The biggest thing with a POS system is support. Where I work (not my dept.) we were locked in a five year contract with a company based 5 times zones and 5,000km away. Adding new printers, configuring printers, connected by cheap off-the-shelf switches and routers, too many people with admin access and employee turn-around losing the people who knew the system. Add to that old and usually proprietary hardware that tends to get damaged faster in an environment with a lot of food and liquids (restaurant/bar). Add to that restaurant people tend not to be technology oriented. I can't see my workplace buying a bunch of iPad or iPod Touch devices just to use a brand new system. I know the staff would love it. If you had an iPad/serving tray that would be interesting too. The perfect system would run on old existing hardware, be bullet proof, very intuitive, cheap and with lots of support every day at all hours.
