The C key on my new MacBook has a subtle but noticeable problem. I noticed yesterday morning that typing C wasn't always registering. I played around with the key and discovered that pressing the top of the key registered a normal click like the rest of the keys, but pressing at the bottom of the key was mushy with no click. I have an appointment at the Genius Bar Monday. I'm posting this to see if other people have a similar problem. Never had a key fail on an Apple keyboard before and I'm worried that this one broke just five weeks in. Hope it isn't an issue with the new keyboard tech. Also -- anyone know what the repair process will be? Brand new MacBook or actual repair? Otherwise, love the Macbook -- perfect as a companion to my iMac and perfectly speedy for what I need -- Web, email, writing.
