While we are on the subject of clever gadgets such as underwater cameras (Monday), this is pretty nifty too, It's a USB stick with a space in the side to stick in a digital camera memory card. It's official techie title is Integral USB 2.0 single slot SD card reader
If you have a space for a digital memory stick in your laptop ot computer, this might not appeal, but if you do not, then this will allow you to upload your camera pics directly into any gadget with USB stick access. Very handy and very cheap £1.22 from Amazon. Love it.
