I understand the issues you experience. I don’t get the point you are trying to make.

I have a cheaper smartwatch and a dirty cheap robot cleaner.

Cheaper smartwatch has e-ink screen, notifications, payment, health monitors, etc. It doesn’t have all possible smart features, but in return I got 30d battery life.

Cheap robot vacuum cleaner is based on basic sensors, no lidar or recognition systems. It gets stuck in cables, it misses 10% of spots, but it captures 2 cup sized ball of dust every day.

I am happy with both. Especially because I researched and found what works for me. Maybe the ‘best’, ‘smartest’ and most expensive products in the market isn’t neccesaary what everybody needs?
