Actually it can only be expanded to two years, not by two years. At least not how I read it.
With anyone, once their device is two years old they're on their own unless they've purchases some kind of extende warranty from a third party.
I do agree with and sympathize with the OP. I'd love re remove iMessage, Game Center, Facetime, Newsstand, iTUnes (I rip my own cd's I don't buy music). ANd I find that it makes no sense that all apps are 'sandboxed' and separate yet the reason for built in apps being non-deleteable is because they are all linked together....seems kinda contradictory to me.
However I also know that Apple is rather infamous for their 'use your device as we feel you should' attitude, and if you want to use their cool toys, you have to accept that attitude and make your own workarounds. You have to accept that the cool devices are made to facilitate the growth of the App and iTunes stores and that Apple likely makes more profit from them than they do the sale of devices. it's like the cell phone company giving you a good deal on a phone to make their profit off your monthly access fee.
I have all those apps (and even more on my iPod Touch) crammed in a folder on the back page and my biggest irritation is the insistence of Apple to keep pulling that danged Newsstand out of hte folder and cramming it on my screen every time I do anything with other apps. I wish newsstand was like iBooks, an option.
The chances of Apple changing their decades old attitude is slim, so as a user you either accept it and find a way to put yourself in a 'works for me' state, or you try devices by other manufacturers. I did consider that, but after struggling with my mom's e-reader and the complete chaos of the Android store, I'm not going to set myself up for that ridiculousness. Way too much work for me and not something I want to mess with. I will submit myself to Apple's attitude because I find dealing with workarounds to be less work than the utter chaos of that other system.
