Things that ought to exist if they don't already

If you have a laptop or a netbook, you might have a cell modem for it.

You can probably already hook that cyberman bluetooth headset to the device. Can you initiate a call that way?

How about a bluetooth handset that can talk to the computer, and has a keypad, a mike and a speaker? Now you can use the very expensive very heavy phone while it's in your bag.
