Hi des44
Here are some definitions ofthe 2:
Bluetooth:
Chip technology enabling seamless voice and data connections between a wide range of devices through short-range digital two-way radio. It is an open specification for short-range communications of data and voice between both mobile and stationary devices. For instance, it specifies how mobile phones, WIDs, computers and PDAs interconnect with each other, with computers, and with office or home phones.
Wi-fi:
Short for wireless fidelity This is another name for IEEE 802.11b. It is a trade term promulgated by the Wireless Ethernet Compatibility Alliance (WECA). "Wi-Fi" is used in place of 802.11b in the same way that "Ethernet" is used in place of IEEE 802.3. Products certified as Wi-Fi by WECA are interoperable with each other even if they are from different manufacturers. A user with a Wi-Fi product can use any brand of Access Point with any other brand of client hardware that is built to the Wi-Fi standard.
A wireless networking technology for PCs and PDAs that allows multiple devices to share a single high-speed Internet connection over a distance of about 300 feet. It can also be used to network a group of PCs without wires. Wi-Fi is spreading like wildfire in homes, offices and public places such as coffee shops, hotels and airports.
Hope this helps.
I would look at a Nokia Communicator 9500 as an option.
