Please, can anyone help me before I go completely grey! I want a gadget. I know they exist coz I have seen them in magazines but as I can not remember what they are called I can not find any details. It is a small thing like a portable hard drive which you take around with you. When you have filled your camera's memory card you can put insert in it the gadget and copy your files onto it, freeing your card for more piccys. Some of these gadget's have little screens which let you see your piccys (and/or video) like a basic Pocket PC. Some can also play mp3s like an iPod. I am about to go on holiday and want one of these to save having to buy piles of memory cards. Any ideas? Please!?!
