Earlier I was thinking to myself how impressive it was that I've had some of my Apple products for as long as I have. I've had my iPod classic for over 5 years now and it's working like brand new. My question is, are Apple products subject to planned obsolescence? That is to say, are Apple products built to eventually become defunct? Or are they build to last for incredibly long periods of time (decades)? For example, if someone buys an iPhone today or an iPad, or even a rMBP/MBA/iMac, how long can they expect these products to last for? 5 years each? 10? 20? Have any of you guys had any experiences with your devices just suddenly going defunct (excluding accidental damages)?
