One thing is a delicious irony, though, given recent anger and outrage over the NSA's abilities to data track. If our governments, UK or US, told us we had to carry a mandatory ID card with a transmitter and NFC, wear a GPS tracking chip 24/7 and that a government snoop was going to read all your letters before they were delivered, and inspect your kitchen shelves and underwear drawers to see what you bought, there'd be riots. But call it a smartphone or smartwatch and people queue up overnight in the cold to buy the latest model.
