As it has been termed, a mobile phone is a mobile phone, i.e. it is a phone which is mobile. So the best use of a mobile phone is when you are on the go or stuck in a remote location. It is one of the greatest technology I can think of!!!! How else can one think of making a phone call and communicating (no matter how trivial) when you are standing in middle of no-where. How many lives has it saved when people called 911 and inform them of a problem when they are stuck in some remote location?? It is one darn good technology, the rest of the stuff they add onto it is just bonus.
So no matter what people say, I say, 3 cheers to it!!!
