I think the author of this article doesn't really understand the technology behind packet sniffing, open wifi, what packets iPhones are sending, etc. The article makes it sound like somehow this "device" (really just a computer - a Raspberry Pi) is somehow some special technology that people should watch out for. When I can do all of these things on any laptop on an open network. And in fact, that's going to be less attention grabbing in a cafe than some mysterious black box under a table. It's a shame that the take away message wasn't that any open network is a security risk, not just when someone happens to have one of these "gadgets", but anyone on the network with a laptop can do the same thing.
