Cufflinks with Wi-Fi hot spot turn you into a digital 007 | CNET

These silver oval ‘links keep your cuffs together without the embarrassment of using some silly analog plastic buttons, and also double as a USB thumbdrive with 2GB of storage and an embedded wireless hot spot.

They can be used to share data and Internet access between smartphones, tablets, laptops, and just about anything else that’s USB- or wireless-compatible.
