One of my posts two years ago suggested it would be a great time to bring back the Spectrum computer or something like it:
The new Raspberry Pi is pretty much exactly what I asked for (though I don’t think it came from my request) . For about £22, you get a computer. You plug in a keyboard and a TV and comms, then start programming. I am amazed it has been so long for someone to do it, but better late then never. Now a new generation of kids can learn how to program by messing about, instead of falling victim to the formal teaching that is provided by schools and university. I have always believed that learning how to hack programs together is the best way to understand what you are doing. You can learn formal methods later if need be. I don’t think hacking is the source of bad habits. Rather, it is more likely to show you the workings of the machine so you can exploit it better. I have seen too many taught programmers make good impressions of being mentally crippled after being forced to think in just one way, any fee-thinking and originality purged.
The Raspberry Pi isn’t the only tiny computer around though. FXI also have one, the size of a USB memory stick, and pretty impressive capability, albeit five times the price. It is easy to imagine how devices like this could really change how we work. I like to travel very light and haven’t carried a laptop for years – even the latest are still heavy and big and just aren’t worth the trouble. I won’t even use an iPAD because it is still obese, power-hungry, and altogether too primitive.Turning up at a conference with a memory stick containing your presentation has been fine as an alternative, but you are reliant on the conference laptop having the right setup. If you could bring a full PC memory stick and run everything from that, that would be better. At home it will be good to put media straight onto your TV without cluttering the room up with big boxes. A Slingbox has done that for years, and smart TVs now do it built-in, so it isn’t new, but this makes it a lot easier and cheaper to provide web and media on more conventional TVs.
On the go, you need some sort of visual display of course but soon we will have visor based head up displays that work with fingertip tracking or virtual keyboards. Then these compact devices will come into their own. You’ll be fully connected and IT capable, but carrying hardly any weight.
Both of these new devices are small but capable, and most of the size they still have left is really interfacing to other devices. The processing guts is much smaller still. There is room to shrink further, and it is clear from these that the era of digital jewellery is almost with us. Imagine the enormous environmental benefits too, if we hardly need any resources to provide for all our IT needs.
It is the curse of futurology that you are never really happy with the stuff available today because you know what is round the corner. But when I can easily fit all my IT into my pocket as a memory stick and wear a lightweight visor as my interface, I’ll be pretty near content. Can’t be long now
