Found this while browing play, 16GB memory pen for jus a smidge over £1 per GB!
Ive got two of the 4GB ones that ive had for a couple of years, really sturdy and compact, and the sliding usb connector is pretty cool to fiddle with when ure bored! The whole white section you can see is your access indication and lights up with a bright orange.
Plus they have the U3 technology so you can install anti virus to protect your usb pen if connected to an infected drive; along with lots of other programs too.
I would definately recommend them to everyone!
