On my flight down here I saw a young boy carrying a sleek black bag on his shoulder. He held it naturally, but with a hint of importance. It took me a moment to see the logo: it contained his Nintendo Game Boy. His generation sees nothing remarkable about traveling at all times with a computer. It is already possible to connect to the network from a palm-sized computer with a cellular link. As computers get smaller and cheaper, we will lose even the excuse of the weight of that black bag or the cost of losing it.
