"They" (Apple, and other consumer electronics companies) want you to keep buying new stuff every year. They've designed the system to come out with better-faster gizmos every year to make you believe last years new hotness is this years has-been. It keeps their profit margins up, their wallets fat, so long as you keep buying new stuff. But does it serve you in any way to stay on that treadmill, chasing the latest hot gear? Do that and you're constantly shoveling money in the direction of computer companies.
