Remember what mobile phones were a decade back? Well I certainly do. They were those queer "portable phones" that one could carry in their pockets and make calls to anyone without having to connect through any connection. "Wireless", that's the word. At that time, mobiles were made for their basic and principle purpose, "a means of contact even from remote areas." Those small screens, dotted digit screens....
Let us take a look at what mobiles are NOW:
Touch screen, HD, WiFi, EDGE, GPRS, 8MP camera and what not. And look at the irony....you don't really need these services at all. True, today's world is such that people tend to be hopelessly after something they want, but in the process neglect what they need. That's what companies have taken advantage of, and to a great deal that is.
Agreed mobile phones are great, I mean when you show your flashy phone among the crowd, it turns many a envious eye....but that's not the point.
Bottom Line - Yes phones are cool great to have one(sweet...totally), but it isn't entirely essential(remember a world when there wasn't anything such as cell phone?).
