I just had my Powerbook replaced with an MBP (finally!)..
And immediately, the "page down" key fell off...
It was slanted when I received the notebook, and I was typing today and it broke off.
I called the Apple Store and asked them if they'd just switch out the key. They said yes.. I asked them if they only had PB keys, they said they don't know.
I'm just wondering.. are the PB and MBP key mechanisms (with the scissors and stuff) the same?
