Keyboard
I underestimated how nice a wireless keyboard would be.
Because the keyboard on my laptop is alright. And I like typing, but I've also started talking more into my computer and started liking it even more.
But the biggest gain is not in the – initially not so certain, but after some testing definitely appreciated, and markedly – improved typing feel, but in the freedom to move further away from the screen and sit in different postures – like in the lotus seat in front of the desk, with the keyboard on the back of my right heel.
And I can even still trigger the voice dictation tool from this posture with the wireless keyboard. (Which feels odd at times, even when I'm all on my own.)
The rotating knob in the top right corner, that I had to put in there by myself – so far it seems like I overrated it. I still change volume by pressing the volume buttons. What's nice is that I can also press it.
And also that I can change the colored background lighting by pressing Fn + Arrow keys on the keyboard. Instead of the keys around the one I press lighting up in light blue I now have the whole keyboard glowing in orange.
