It has a dial on the front to choose settings. Potentially a great idea to skip quick to the one I want - BUT the damn thing can only detect 1 step of change about every half second. So if you fast-turn it 4 clicks, it still only moves one step. So you have to stand there, slowly turning it, click, click, click, click....
The dial is the biggest design feature on there. Massive. Right in the middle. Bright lights all around it. But they couldn't even be bothered to make it solve the one problem it was there to do.
It's the kind of thing that'd make you reject purchasing it if only you'd thought to have tested that specific bit of it before buying it.
Honestly, I wish that they would make appliances with physical controls as opposed to digital. At least those are easier to fix/mod on your own.
I think if someone did a kickstarter for a very simple physical buttoned digital camera it would do very well.
Caveat: said Arduino may need to sit between the rest of the buttons as well, in case inputs must be given in sequence.
Possible benefit: switch the Arduino for something from the ESP family, and you could feed instructions to the machine over Wi-Fi or Bluetooth. (Which could take the form of a dedicated wireless button panel above the machine with macros for frequently-used options.)
(Hmm. I can tell there's some over-optimization in here, but I'm not sure _where_.)
You can tell the execs that approved that were probably impressed watching someone else demo it but probably never used it themselves.
Jobs would have spotted it was rubbish immediately.
