Do I still need a mobile?

Of course as a confirmed gadget freak, I can't really be without one, but I communicate so much with IM and and email (particularly since Jenny has caught the IM bug), I am beginning to wonder if I do actually need one.

I suspect it's now more 'want' than 'need', but since I would feel uncomfortable walking around without one (there are personal safety considerations apart from anything else), I think a move to pay as you go is in order.

Soon. I need some GPRS bandwidth still...
