So DON'T STICK THE BATTERY TO THE CHASSIS
Very simple. Mine is away for the three week holiday. If Apple had pursued a more... repairable design, they would have saved a packet on this recall, and on every other free repair that required the battery to be removed or replaced. Make it like the previous generation where all you needed was a screwdriver...
One change I hope to see with Jony leaving is to stop obsessing over thinness and instead focus more on repairability. A man can dream, can't he?
