Earlier quoted context omitted.
It is! My most hateful comment is about the Apple Air: "Please provide an example why a screw or removable panel would provide less value to the consumer than gluing the thing and making it impossible to replace the battery on your own. I eagerly await your response."
Reliability. Screws come loose, especially when flexed in a pocket etc. Its considered a win in mechanical engineering circles when you remove a screw from a design. I look forward to metal-air batteries, where the charge can be expected to exceed the lifetime of the device.
Not to run too far away from the actual content of the post but...
I thought metal-air batteries didn't produce a high enough current to be used in devices requiring much more juice than a hearing aid?
