I actually almost prefer the keyboard, I feel like having less travel means I have to press slightly less and can type marginally faster on my Mac keyboard than a normal one.
I’ve not had to replace anything, I’ve had a key that felt stuck once or twice, but after a good bash it fixed itself. But it is almost 3 years old now!
The Touch Bar is a bit useless I’ll admit, but using BetterTouchTool I’ve made it more useful. Shows me my company share price live, tube status and the time of my next train as well as shortcuts to my most used apps.
