I've seen novelty cufflinks with all kinds of absurd functionality before, but for the life of me I can't figure out who would ever actually need the ability to create a wireless hotspot while wearing a fancy suit or tuxedo.
At a wedding? A funeral? While being knighted? Even an impeccably dressed secret agent would most certainly have their own custom tools for the job, and those who might find them handy -- like IT professionals -- probably don't dress with the need for cufflinks.
And while one of the cufflinks can be connected to an online computer to create a Wi-Fi hotspot, the other one is nothing more than a 2GB flash drive that isn't even wireless. Were you able to wirelessly send files to the other cufflink while wearing it, I could maybe see a justification for their $US300 price tag. But you can't, so I just don't get it.
