Bluetooth connectivity is ubiquitous today with cars, computers, and game consoles all sporting the connectivity option. Despite how common Bluetooth is in consumer products, there are still a number thin and cheap notebooks and netbooks that ship lacking Bluetooth.
The best way to add Bluetooth to machines lacking the feature or to machines with older Bluetooth specifications is with a small USB adapter like the new Cirago BTA3310 or BTA6310. The 3310 has a range of 33 feet while the 6310 has a Bluetooth range of about 330 feet.
Both of the adapters are Bluetooth 3.0 compliant and support EDR with 2Mbps and 3Mbps modulation modes. The 3310 adapter sells for $29.99 and the 6310 adapter sells for $39.99 and both will hit stores by the end of June.
