Excerpt: The Lexar JD FireFly is an amazing little piece of technology. Emphasis on little. approximately 5 cm long, this thing doesn't take up much space. The only problem is, that makes loosing it that much easier. Unfortunately, the one that I purchased didn't come with a lanyard (necklace type of clip), even though the cap is made for one to be attached to. Oh, well. I'll just keep an eye on it. The device I received came with Google software.
