Possibly. That is if you have an iPhone and Apple has anything to say about it. According to PC Magazine, a new Apple patent application published last month describes a system by which you order something (say a deli sandwich) with your iPhone, which is then prepared and ready for your pick up when you arrive. Assuming this patent application is not merely Patent Lawyer bait, we might see some embodiment of this system this month MacWorld Expo 2008.
Although, truthfully, I am actually looking forward to the copy and paste function a little more than a ham on rye.
