Many laughed at the original Apple iPhone with its built-in battery, including me. Within five years almost everyone mimicked them,
I have an Apple iPod that won't hold a decent charge. It's also not getting much support from Apple. Forced obsolescence, yet it looks as good as the day it left the factory. No scratches. I'm annoyed that the device is not maintainable.
I just purchased an Apple iPad Air. 10.9" display. 256 GB storage. My original iPad Air is about the same size. 64 GB storage. Not getting updates from Apple. More obsolescence, yet the device is spotless. The only thing wrong with it is age.
I welcome the prospect of the return of replaceable batteries. Likewise, a better strategy of support would be welcome. Especially at a time when manufacturing new electronics is getting difficult due to supply chain problems.
Palm Pilot beat them to by years.
