Is resilience the flip side to repairability?
Since I got my first phone in the 90s I've replaced each one after about two years. Partially because of new features of the new phone, but mainly because the old one was now knackered. Scratched screens, fluff in the screen, buttons not working properly, etc. This was true from my many Nokias, through Blackberries and finally an iPhone 3GS. Apple were even quite nice about the 3GS and out of warranty gave me a new one for free when mine got fluff under the glass.
I bought an iPhone 4S almost 3 years ago and it is the first to break the mold. I got Apple to replace the battery last month for £55. Other than needing that it is as good today as it was the day I bought it. I can't help but think that maybe making a device both small and really robust is somewhat related to it becoming harder to repair.
