Unfortunately, the "butterfly" keyboard is a major failure. Let's be honest: it stinks (to be polite). First of all it is NOISY. Then it is uncomfortable. And I find I'm making many more typing mistakes than with the previous "chiclet" keyboard.
Sometimes I use my wife's Macbook and use her chiclet keyboard: silent, comfortable! A pleasure to type!
Then I have had two keys going crazy. First the one with number 4. It would stick and not type anything. I noticed it because my password had a "4" in it, and I would get login failures all the time ... That drove me crazy but somehow fixed itself. I imagine some dust found its way underneath the keycap ...
Now suddenly key "E" started misbehaving. The most frequently used letter in English and French (the languages I do the majority of my typing). Last news: the key just popped out ...
I am going to see the local apple store this afternoon. God knows how long they will keep my macbook for. This is a professional device. I use it every day ...
As soon as Apple comes with macBooks with a decent keyboard, I am thrashing the one I have now.
