For a while, I have been wondering if there isn't a way to use technology to help town centres and that could be incorporated into retail models.
Take the complaints about M&S for example, they don't have all the garments in all the sizes! What if they kept a limited number of items in all the sizes in stock so that they could only be tried on? If you were satisfied, you could order the item that fitted and a new one would be delivered to your house at your convenience. Nothing to carry. Technology used but not necessarily by the customer. Clothes displayed well too, no crowded racks. You could also have a local 'purchases' area in the town centre where everything you bought could be assembled, either for collection by car or again, delivered to your home. You could leave your car behind and go by bus!
You could see/try before you buy, use the internet but not go near a computer.
A bit radical perhaps.
