If you're running out of space on your memory cards for your camera, you might be thinking about buying another. Prices are falling all the time, and now you can pick up 16GB for around £20.

This SD card, however, only holds the equivalent of about 256MB of photos. Specifically, it holds exactly 60 4 x 6-inch snaps in little plastic wallets. On the bright side, though, you don't need to plug this card into a digital camera to view the pictures, you can just open it up.

It's available from Spinning Hat - a UK webstore that also offers a SIM card to store your friends' contact details in. It'll be arriving in April, though you can pre-order it now. It costs £10.
