Re: Even maintenance can be hard
It took the local independent phone shop 10 minutes to replace the battery in my spare iPhone - done on the counter as I watched (and it cost me £20 - parts and labour).
I don't think my current iPhone will be as easy, but Apple quoted £69 for them to replace it - which isn't far off the cost I've seen for genuine (i.e. not cheap knock-offs) replacement batteries for the old Nokia and Motorola mobiles lying around in the granddaddies toy boxes.
R2R is necessary - but let's not try to justify it with arguments that can easily be undermined.
