Gadgets

I do not understand why do people get obsessed with gadgets? Especially the new or latest one.
Is it because of getting more and more modern?
Is it because of not wanting to be an outcast?
Human are greedy creatures indeed.
I used to keep up the technology development. I got envy if my friends used the gadgets that were more sophisticated and better than mine. Or if they had something that I had not have, I bought it shortly thereafter. (ex:Nintendo things) After I got it, I got bored, I dumped it.
But..
I am getting tired with the development. Technology is endless.
From the first, I am not interested in iPhone, iTouch and iPad. I do not know why. I found it they are boring for me. Nothing special. I dumped my iTouch until it has been covered with dust and the battery has sorely leaked.
I have a MacBook. It is because I need it for my college. iPhone, iTouch and iPad.. they are just useless for me.
Thus, I do not understand with people who want to queue for a long line to get the latest iPhone, iPad or aaahhh whatever! Can't you just wait for several days? If you wait, will you die immediately?
The other case, there are people who sell their organ (ex: a kidney) to buy those things. What the.... Are gadgets really that important rather than the health? So absurd! Where the heck all those people's brain?
It seems technology plays an important role nowadays and people can not live without the technology even just for a single day. Technology really drives the world and people in it insanely.
