When you connect a new device to a ‘smart’ tv, you must pay homage to the manufacturer with a ritualistic dance. Plugging and unplugging the device. Turning them on and off in the correct sequence like entering a konami code.
Every time you want to switch devices, the tv must scan for them. And god forbid you lose power, or unplug something. You are granted the delight experience of doing it all over again.
I have fond memories of the days of just plugging something in, and pressing the input button. Instant gratification. It was a simpler time.
What is some other tech that used to be better?
Oh you mean replace. Swap means (for me) to switch from one battery to another on the go. Of course, replacing batteries in any appliance should be easy and cheap. Maybe not necessarily being performed by the customer.
