And, Apple should be better at UI design than this. They were once, and not that long ago, but I think the UI team they've had for the last, oh, let's say seven or eight years -- going back semi-arbitrarily to iOS 7, but steadily infecting all other platforms -- have prioritized aesthetics over usability.
So I would agree with their design decision: make an elegant remote, use voice dictation for search and the like, if you need a keyboard, use your iPhone, and if you are not happy with that, get a dedicated keyboard. If you are not happy with THAT, well ...
But I can understand where you're coming from, I am just very frustrated that this user-interface-design-genius trillion dollar company can not change the input mechanism of one of their most used product from the:
a b c d e [f] g h i j k etc... Backspace
model with only <-> movement and no way to make an input correction other than backspace, to something like:
a b c d Backspace
e f [g] h forward
i j k l backward
m n o p
Which is the way almost all other TV-centered apps I use function and works much better.
I don't need a dedicated TV keyboard. As I said, I work around it by using the TV apps, but it's annoying, and the most annoying part is that it's probably annoying on purpose to get people more on their phone.
