Seems everyone gets that, but thinks it's an anachronism and that they
should be smaller. The average iPhone is not hardened against EMP or
radiation, relies on ambient temperature, etc as well as planned
obsolescence of a couple years (similar to desktops).
Anything built to last, especially be user serviceable and field reparable
is going to need to be bigger. Hardening them to take damage, redundancy,
even more so.

should be smaller. The average iPhone is not hardened against EMP or
radiation, relies on ambient temperature, etc as well as planned
obsolescence of a couple years (similar to desktops).
Anything built to last, especially be user serviceable and field reparable
is going to need to be bigger. Hardening them to take damage, redundancy,
even more so.
