I just learned that the Latitude D630 (runs Windows XP Professional) is supposed to get used with a 'Bluetooth' portable bar code scanner (Library inventory application). The technical (Library) person had referred to it as 'wireless' but obviously it is not the WiFi, which we ARE using to connect to various WiFi access points inside the Library. Does the Latitude come with 'Bluetooth.' Is Bluetooth even available with it? If one has both WiFi and bluetooth with it, is the system capable of running both concurrently (using WiFi for the network connection, Bluetooth for the bar code scanner connection)?
