If such a thing existed, you wouldn't be able to use it to disable Silurian ray guns, since I don't think you ever encounter them in your daily life Emily, but the apparent ability to be able to open any door by just pointing the screwdriver at the door seems very handy, so i guess it would be a better choice than the PS3 Move. How is it supposed to be able to fix computer based things, do you just point it at the device and it magically fixes it and what exactly do you mean when you say that it fixes a device. Does it make sure that the device does its prescribed function properly, if so, it would have to keep up with all new technology and know exactly how everything works to be able to fix anything or does it just happen to be able to read your mind and make the device do what you want it to do. Making money spew out of an ATM seems very useful, I would want it if that was its only function, but every ATM has security cameras now, you would have to watch out for the security cameras while you are stealing money from ATMs with this magic screwdriver. But, I guess if the magic screwdriver can apparently fix any computer based thing, then it could also break them, so you could just point the screwdriver at the security cameras and disable the cameras. Also, how does this device cut rope and what exactly do you mean when you say that the magic screwdriver can scan lifeforms for various information, what information exactly does it give you and how does it give you this information, does it bring up a holographic screen or does it just plug directly into your brain and transfer the info directly to you.
In other words, this sonic screwdriver, is the biggest load of **** that I have ever heared of and it has only decreased my opinion of the tv show.
