Super ridiculously easy, even before they had their installer. I got pixel 1 years ago, second hand, just for fiddling with it. It was the shortest fiddling in history and the phone was ready to be used in minutes.
Nothing like the experience I had in Samsung for example.
Alza sells Eternico mouses/keyboards. It’s their in house brand. It’s kind of Czech/European made, but in reality it “Made in China” on the bottom.
I’m curious about this as well, but I really doubt that any electornics, like mouses/keyboards are really made in Europe. At least designed in Europe doesn’t count for me as European made.
