What about a smart version for the Airport?
The smart trolley seems a good idea although the supermarkets might jib at the idea of sounding an alarm if you buy something that's not on your list!
What I would really like is a smart trolley for my hand baggage, that will follow me round the airport, negotiate its way past all those places where it seems trolleys aren't allowed and deliver my hand baggage and airport purchases safely and smoothly to the terminal departure gate. Surely it can't be that difficult with the technology we see in this article? Perhaps the real problem is that airport operators are somewhat less motivated to help their customers than the supermarkets!
