I get a brand new phone every 2 years for free. I paid into the system once about 6 years ago, and now the sales price (or trade in value) of my 2 year old phone is equal to or higher than the brand-spanking-newest phone on the market. Now when I say "free" what I mean is that I don't pay any more to have a new phone than I would pay for identical service if I were to keep my phone forever. My plan rate is basically fixed no matter what device I use.
So instead of having a CDMA locked phone with dial-up modem speeds and 8GB of memory and a mobile OS which is no longer supported (which also means being locked out of revisions to the applications I run), I have this year's latest and greatest, with a pen to take notes on the screen, enough space to hold everything I need, two options for biometric authentication (if I should choose to use them), a camera which is as good or better than my last point-and-shoot, significantly more secure storage, and internet that is faster than all but one of the land-line providers to my house.
I would love to have a phone that never needed upgrading, sure. But I'll bet Greenpeace didn't ask if you wanted a phone that was insecure, limited in usability, and had poor performance on current generation software.
