Why do people love mobile phones so much?

It just seems like these days people are obsessed with mobile devices. It’s to the point now where people actually identify themselves by a certain mobile technology. Statements like, “I’m a iPhone guy” or “I’m a BlackBerry loyalist” just seem strange to me. People will wait on lines for hours to wait for the newest thing from Apple and pay good money for spots in line closer to the store. I mean, don’t get me wrong I use a BlackBerry and it works fine for me but people keep telling me that I should convert to their preferred mobile device. I just don’t get it… any thoughts?
