We're still not sure about the wisdom of having a USB key so small that it can get lost among pocket change but, if you want something truly tiny, this is it.
The appropriately named "Nano Flash Drive" from Imation comes in storage capacities ranging from 1GB to 8GB, but the size remains the same for all of them: 1.75 inches long and a half-inch wide, weighing a scant 1.3 ounces. Not surprisingly, Imation says it's the smallest flash drive of its kind that it offers.
In our view, its smartest feature has nothing to do with the storage technology: It has a swivel cap that can't get lost. Then again, if you can't find the key itself, that won't matter much.
