Query: Tiny & Cool

I just picked up one of these for use in some programming and GIS courses I am taking after work. This is thing is tiny, about the thickness of 2 or 3 credit cards, less than 3 quarter of an inch wide and less than 1.75 inches long. This USB flash drive is dwarfed by all others I have seen.I have seen this item packed with a "sleeve" that resembles a nomal USB keychain that you slide the item into though I am not sure why because it functions great without this "sleeve" and with it the size is the same as a normal USB keychain. When I received mine it arrived with a credit card sized, though obviously thicker, carrying case that holds two of the PQI USB flash drives. I actually carry it in my wallet.I have had no problems since receiving and using this item. In fact I plan to purhcase two 1gb models within the next couple of days.
