LaCie 8GB MosKeyto Nano USB Flash Drive
(includes 8GB subscription to online storage Wuala)
I've been after a good performing nano USB thumb drive for my netbook that doesn't protrude much from the side. This pretty much fits the bill - ITS TINY!
To be honest, this seems a little expensive compared other USB flash drives of the same storage size however its size, performance and fact that it comes from a reputable company makes it a hot deal in my books :D

The LaCie MosKeyto measures less than 20mm and weighs just 10 grams, making it one of the smallest USB keys on the market. It offers capacities up to 16GB, and becomes nearly invisible when plugged into your computer, and can even travel alongside it in a protective sleeve or briefcase - just plug it, and forget it. Since it lies flush against your device, you'll never lose it, and there is no risk of damage to the USB port, computer or key if the drive is knocked or bumped.
