The only reason Apple makes so much money is reselling their product over and over again every year. Each year they release a new model for I-Phone, I-Pod and now I-Pad. Each version has some new features which make it a must for Apple fans, these fans go out buy the newest phone , Pad or Pod.
My Uncle has had every I-Phone since the first one launched, he has had over 7 I-Pods according to his bragging. He also has had several Apple computers and now a Apple TV. He was bragging at Christmas how he will soon be buying the new I-Pad as soon as its availible.
Those are the consumers I'm talking about. Where PSP and DS do have new models Nintendo and Sony etc...etc... don't upgrade every year. If their was a new model with new features every single year consumers with money would blow big bucks and we would probubly see similiar sales.
Also as it works with my uncle , these Apple fans upgrade constantly selling their old Pods, phones and soon Pads to consumers who couldn't afford the newest model. My uncle gave both me and my sister two of his older I-Pods. He gave other family members his old I-Phone and what he didn't give he resold.
So now those poorer consumers get a refurbished or used I-product. They get hooked and as soon as they can afford a new model bingo they buy the newest model. I wonder how much of the total sales are repurchases? Theirs no doubt they have major selling abilities but a huge part of that is resale.
