A new version of bluetooth was launched last month. It will be a while before we see products in the shops of course. It uses the same communications protocol as your wi fi, so Bluetooth 3 will be much faster than version 2 and can be used for bulk transfers of data or for video. It will allow for mobile phones and for that matter netbooks to interface wirelessly with a wider range of external devices - see this Nokia video to se how this might work.
