Why it took so long for these products to actually materialize I will never know. I always have kept a USB drive on my key chain but I have had issues with it breaking or being a little too bulky or fragile. These new ones from Lacie are all metal and the shape of your keys so they fall in line super easily. Since they are a whopping $27 for 8 GB I think I will be picking one of these up when they come back in stock. Check them out: Lacie Key Drives
