Oh Bluetooth, it seemed like just yesterday you were a fledgling technology. Now you’ve made your way into nearly every mobile phone on the market and are decent for file transfers and do the whole stereo music thing. We’re proud. The number of Bluetooth products shipped to date has exceeded the number of PC users in the world—that’s a hell of a lot of products floating around. The current goal of Bluetooth is to keep growing and ship two billion products alone in 2010. Just in case you’re absolutely clueless, Bluetooth can be used for wireless headsets, file transfers, wireless peripherals, and about 1,000 other things (the aforementioned being some of the most popular). Good job Bluetooth.
