The best way to think of Bluetooth is as a wireless alternative to peripheral cables. It offers a relatively slow wireless link (around 1M bits/sec) that is suitable for applications where serial ports or low-speed USB is currently used. Do not think of it as a competitor to 802.11 wireless networking. It is possible to establish IP networks over Bluetooth links, but (as you might guess) the performance is pretty horrible. Bluetooth beats 802.11 at two things: power consumption and design simplicity. BT devices suck way less power; that's why you see BT cell phones popping up but none with 802.11. BT chipsets are also *much* easier to design around than 802.11, allowing it to be included in compact devices like phones and PDA's.
