Here is a list of must have gadgets that I am thinking about this Christmas:
1) Bladerunner II - Remote Control Helicopter: Click here
I always wanted a remote control helicopter when I was a kid, now they are small and have little computers in so that even idiots like me can fly them around the living room without worrying about decapitating someone in the local park.
2) A Green Laser - Click here
These are a bright laser beam, bit of a gadget - pretty expensive for what they are - cool all the same.
I am in the process of adding more stuff to this list - just in case Santa (/ my wife) finds it before Christmas :)
