The annual gadget extravaganza is under way in Las Vegas and thousands are there to digest the announcements. I read, and like, the term “intelligence of things” from the event, and manufacturers are upgrading their products with technologies such as GPS, internet and bluetooth to inject connectivity and new life into them. “Everything connected” appears to be the trend and connectivity will spread beyond computer-related devices to everyday products such as meat thermometers and toasters. Hardware will be worthless without the app.
