For all of Apple's Green credentials and use of eco friendly products etc, the iPhones have a remarkably short life, even for modern e-products.
I wonder how many of the original iPhones are still in service? What about the iPhone 3G? To say a refurbished 3GS is worth so little... Just makes you think is all, maybe I'll skip the iPhone 4S/5 and wait for the next installment...
I'm not sure that is the case; I was thinking more that if you ignore the 'traditional' long lifespan of apple products, an analysis of the iPhone would show that for a mobile phone, it has a remarkably long working life.
Just think; before, you would get a Nokia or SE on contract;
Probably less than 6 months in, it's more than a little shabby, it was virtually outdated when you got it (as most tended to have some features at the expense of others, and many of it's new ways of slicing bread were supported for almost a week), hard to get cases or accessories (short lifespan of a low markets are model with eccentric implementations), software is never going to be updated again etc etc.
Network offers you a refurb or something at a cost, and updated contract, and...
Your just-a-few-months-old phone gets shoved in the back of a drawer (barely worth listing on eBay)
I used to work in the industry, and it was rare that someone would still have the phone after a year. Even now, I see my coworkers flipping through HTC smartphones, while the rarer original iPhone and (admittedly v. Popular) 3GS carry on.
It's probably due to this lifespan that the iP4 appears to be almost outnumbered by the older models.
