This next product feels like something that Q would give James Bond before a mission. The Spy Glasses are for those times you need some video footage and sound of something for later use.
The Spy Glasses have 32MB of onboard memory, which I'm guessing isn't much time for video. I believe you can upgrade it with an SD card, but I wonder where you will stick it.
The price is pretty steep though, as there go for about $1600 USD.
