Scrabbling around for money to fund breaking my iPhone contract to get the latest model, I found that I could raise £250 by selling off old bits of electronic rubbish that I didn't need any longer and were just cluttering up my cupboards.

I started feeling uneasy when I remembered that the 3GS isn't really much of an upgrade. Surely there are better things I could do with this found money, I thought. So I'm giving it to ComputerAid, who will use it to refurbish PCs and send them to people who will really benefit from them.

I'd like you to join me. Don't go to the Apple shop today. Donate what you can here instead.
