No, it is certainly possible to come up with an innovation that allows progress.

But the tone I get from discussions about repairability and performance is that it would be trivial to make the device, if only businesses wanted to.

However, given the fact that it hasn’t happened yet from a variety of alternative manufacturers, the probability seems very low that the ideal device is possible with current technology at a price that is viable.

Basically, it is a competitive market (or was), and what won out was what was possible. Barring some leap in technology, it is unrealistic to assume we can do better without suffering tradeoffs.
