I just bought a newly refurbished 12" powerbook this month, and noticed something odd. It seems that the top middle of the keyboard is a bit higher(not a ton, just a bit) than the rest of the keyboard. This bump seems to apex right underneath the F6 Key. It also it seems that the sound keys (F4-5) arent as responsive as the rest and the F1 Brightness key really needs to be pushed to work. Is this normal on powerbooks(I really cant remember noticing this at the apple store on other models, but I wasn't really paying that much attention to keyboard flatness), or could it be when apple refurbished it, the keyboard got put on incorrectly? I'll try posting a picture of this later when I get home.
