In regards to your second statement. I believe that by making a product more accessible helps everyone. I have had great user feedback from a really young age group. At a recent show I had a couple of parents who had to drag away young children.
Another area of discussion to your statement is that even if a 60 year old ‘technophobes’ die out, there is still a good 20 to 40 years of live left in them. And this is a VERY long time in the world of the ‘Gadget’.
One of the most important part of my designs being designing the whole ‘net’ experience from connecting to a ISP to hardware and finally how the interface and website works. I believe that by designing the complete experience will help create better and more accessible products.

About the power of the RFID signal. I wonder if the new RFID company, Mojix, (www.mojix.com) would be of any help. There new system reportedly has blown away previous distance limitations.

2) I do wonder about the life-span of the concept. I agree that the integration of RFID and flat screens can have amazing possibilities (interaction with the all-in-one “personal identity card” that the western world seems on the road to adopt), but this particular application seems geared towards older or less technically savvy folks who need a interaction metaphor they are more familiar with. Some might argue that the less technical demographic (grandmothers) that need this is going to be in steady decline as each tech-savvy generation is born. Thus the value of this system might be short lived. How would you respond to such a statement?
