Ha ha ha, great story :) Well, it's al about how we take today's technology for granted and don't care if it breaks isn't it? I have a couple of "out of date" phones lying around and wouldn't feel bad if I blew them up some way. Just for fun. But 30 years from now people probably will look at it and scream "nooooooo, how could that guy be setting fire to an iPhone 5?!!!" It's just how it works. But if you're smart, have patience. Nearly every piece of tech will be worth more than it is today 15 years from now... (ignore that last sentence if you're 90+ years old)
