PS: I forgot to say to David, you should dig a little harder regards "Open Hardware" systems in the sense that mean exactly that, Open as in the entire hardware is auditable and certified free from nasties.  Broadcom kindly even released to the Pi users, data for a component used on the Raspberry Pi, because until they did, it was the only part of the Pi that people weren't 100% sure about.  So there you go peeps, a turn-key way to help protect yourselves from all this crap, just grab a £25 Pi, stick the pre-installed Debain-based OS into the SD card slot and switch it on.  You have a dedicated, self contained computer and OS that was not designed to manipulate or spy on you.  You can use it for the net, your banking, watching 1080P (it's silent, no buzzing fan noise), whatever you want, keep it totally seperate from your main computer.

Perfect.
