I still have a mobile but it does not leave home. I do not make or get many calls so it suits me to not be contactable at all times. Skype on the iPod Touch is how I return all my calls. As for emergencies, I am not going to let fear motivate me to carry something; there is only so much space in my pockets and if I am running from a tidal wave in December, 2012 then I doubt my mobile would help.
