We've already posted some images of the Tomy Takara Transformers Device Label
Tigatron and Ravage 2GB USB flash drives, but we haven't seen much on the actual software that comes with. However, we have some screen caps to show you today.
Each flash drive comes carrying the "Transformers Desktop Defender" software by Toshiba, which is pretty much a digital desktop toy of Ravage or Tigatron (the software can be set to use either) that prowls around your Windows desktop.
The app runs from your task bar once you set it up, and you can change the options to have it auto-start when you insert the Device Label drive in your PC.

Other options (pictures attached) are to have the character "roar" (no sound), "eat icon" (pictured), "jump," or "transform." You can adjust how frisky or fast the character is as it jumps around the desktop, and each has its own abbreviated bio & tech-specs. The character animations are crisp and entertaining, and a nice added value to these drives.
I picked up the Device Label Tigatron, and as others have stated, it is a really nice item. ¥3192 at Joshin Kids here in Japan (about $35.00). Pricey perhaps for a two gig flash drive but the desktop toy is a nice and unexpected addition.
