LaCie has always made very nice looking hard-disk related products. I myself own a few LaCie drives—so when I heard about their new Carte Orange drive, I was very excited. $149.99 will net you the 8GB version which is about the size of a credit card. It needs no drivers and is USB 2.0 thank god. A 4GB version is available for $99.99 which is a very nice price for what you get. The sleek orange and metallic design is a nice compliment to any cluttered office desk as well.
