Apart from that, I'd be inclined to get a bluetooth dongle for the laptop, and a bluetooth phone. My SE Z600 has the lot - BT, IR, 3-band, clamshell, and works with no fuss with IR and BT to the iPaq and the desktop.
A second-hand SE T39m (flip, BT, 3-band) is cheap and they work! The T68i is similar but I don't like "keylock" phones.
