Oh, yes, I know. I usually source Mac parts from iFixit though, they provide a warranty and are a known quantity.
I'm used to repairing my computers, but the broken one was wrecked (it still booted, but the case was bent around the battery, and the screen was broken).
Changing the keyboard of the new one would void the warranty, and having it changed by Apple staff would cost half a new notebook.
So I type QWERTY on an AZERTY keyboard. The only issue I have is the closing paren, (<shift> + <0> in QWERTY) is next to the corresponding key in AZERTY (<-> in QWERTY), so I end up sometimes typing underscores (<shift> + <->) when I want to close parentheses.
I touch-type for the most part, but that key is too far from the home row for me to hit reliably, so I end up looking and mistyping anyway :-)
The Mac parts are usually 2 or 3 times as expensive as the similar PC parts.
