I remember reading somewhere that Bond gadgets become true after something like 30 years, however I suspect that this pace of development will be speed up dramatically as time goes on. Some examples off the top of my head: GPS - there's an old Bond movie with a analog 'homing device', weapons on cars, cars that can drive on the road and fly also, 'stealth technology' like in Die Another Day (in development).
Getting back to movie inspired OSs, the guy who designed the amazing gesture interface behind those in 'Minority Report' started a company and has prototype UI in development:
