Regardless though, the main point I'm making is that it pays to have an 'old school' backup to forms of modern technology, just in case it should prove useful, and where possible I always try to do that. I mean, say you've broken down and are stranded in the middle of nowhere with a flat battery. what use would your sat-nav be at telling you where you were or how to get home?;)
My motto? Never become TOO reliant on tech!
