I fear that these devices are going to become less and less usable, not because they arent physically operable, but instead because companies like Apple are allowing them to become bricks if the owner doesn't pre-empt their demise or recycling. It's done today in the name of theft deterrence, but once these machines end up in drawers and storage lockers for years, I doubt most people will be able to unlock them successfully, rendering them sadly useless.
