The Bluetooth standard has many advantages. It provides a reliable and secure connection between the two devices and facilitates easy data exchange.
However, in the age of Wi-Fi pre N, bluetooth suffers from poor performance -- voluminous data exchange will take a long time.
Things could soon change, with the Bluetooth protocol piggybacking Wi-Fi. The specifications of the "Alternate MAC / PHY" will be unveiled in 2009 and will, depending on requirements, automatically and transparently switch the protocol from bluetooth to Wi-Fi, which is on the same waveband.
This will be interesting because the bluetooth is much easier to configure for a point-to-point connection than Wi-Fi
