BBTS post this little item earlier today:Star Wars R2-D2 Original Sound Virtual Laser Keyboard - Star Wars Electronics Electronics.

I doubt I would ever pay $300 for one of those, but I think I'd be closer to buying one if it was TF themed. Like the keyboard being emitted from a G1 Laserbeak on a perch or on Soundwave's arm or maybe being sent out from G1 Hound's Hologram gun.
