What you see here could very well be the world’s smallest Bluetooth adapter. Don’t let the blown up picture deceive you, because the Princeton adapter sits nearly flush with the side of your laptop, as you can see from the generic notebook depicted in this rendering. The body is ridiculously small, probably measuring not much more a few millimeters.

Better still, the adapter isn’t stuck with some aging wireless technology either. It’s about as current as it gets with full Bluetooth 2.0+EDR, ensuring that you’ll get the fast data transfer you’ve come to expect from the wireless standard. It’s also noteworthy that the Princeton Bluetooth adapter is compatible with both Macs and Windows-based PCs (probably Linux too).

Yup, this thing is one tiny piece of awesome. More information (in Japanese) can be found here.
