If Bond is given a gadget, I want it to be something that could spy on his target - pin hole cameras and microphones to spy on his enemies etc.
Or kill/defend against his target. Bond isn't just an intelligence gatherer. His just job was to destroy "the threat behind the spy, the threat that made them spy" to quote Fleming.
Take a hint from Spooks (known in the US/Canada as MI:6 i think) for realistic gadgets
Nah, Bond should be somewhat surreal and larger than life. SPOOKS/MI6 is too bland, everyday, right-on, and colourless. I'm already concerned about some of the SPOOKS-vibes we're getting in the London scenes of SKYFALL, but I hope I'm wrong.
Look to the gadgets Fleming used. Red Grant's book gun, Rosa Klebb's telephone gun, poison-tipped knitting needles, cane gun, desk gun, camera case bomb, and cyanide-firing gun. In fact, just think of an object and put a gun in it.
