This is a little something that has had my colleagues and I talking about for the last few days, and I thought I'd share it with you. Like most folks, I have a cellphone, and recently I got a new model. By contemporary standards it's nothing remarkable - the size of a small candy bar, it offers the following: music and video playback Internet access text messaging a digital clock personal organiser video games oh yes, and you can make phone calls as well It occurred to me that when I was my son's age (14) in 1974, this device, which we now take totally for granted, would have been a thing of incredible wonder (anyone around at the time will recall the excitement generated by the first digital watches or Pong and they are like knapped flints in comparison). But what single feature of a cellphone would generate the most excitement or discussion? Most of my colleagues think it's the Internet, and I agree, but other colleagues say that the Internet isn't an intrinsic part of the phone, just something you can do with it, and what would really impress seventies people would be the compact size. What do you guys think?
