I haven't read the
linked-to article, but it's a really interesting idea.
I saw my sister's usb mp3 player today - she just sticks it into any computer and copies music across. Imagine that but with its own operating system that enables you to access all your personal data, and even browse the web / send emails - from anywhere. All you'd need is a usb slot, magically also connected to the internet somehow, and a screen. Infact, just invent decent cheap holographic displays and then all you need is a special net connected usb slot. It'd just be like connecting your electric shaver into the electric shaving point in a hotel room.
I declare this the future.
That's all.
