iWant vs. iNeed

So lately I have been having the true desire to have an iPhone. But every time I start to think about it I realize that there are many more important things to spend $30 a month extra on instead of a cell phone... on account of I already have a completely functional cell phone.

Eventually the world will become an iPhone... So I figure I will just wait and let the iPhone take its course... sooner or later I will have one, but I'm in no rush.

iWant- an iPhone

iNeed- many other things.
