This is an article that discusses the 5 W's of Bluetooth, the who, what, where, when and why.
"The story of Bluetooth technology is an historic one. It includes a king, an army 11,000+ strong, over two billion dedicated fans, global recognition and a decade of perseverance and hard work. The story of Bluetooth is at its heart a story of evolution - where we are today is a long way from where we were 11 years ago"
For the record, I'm still not a big Bluetooth fan. My headset forgets about once every three months it is paired with my phone and I cannot pair my Pocket PC to my Windows 7 based netbook with anything but "0000" as the passkey (hoping that is a build 7000 bug). I love it for my headset and I use BT for tethering unless there is an outlet nearby - I'll opt for the USB cable which has charging goodness, but given my druthers, I avoid BT when at all possible. But I know I am unique in all of my issues with Bluetooth. It works perfectly for everyone else, and I recognize that.
