Has anyone been to the Apple stores and actually worked with a 12" G4 Powerbook? The button below the trackpad (equivalent of a mouste click) looks really flimsy! when you off-center "click" on it, it sticks and doesnt come up, its not smooth like the iBooks or the 15" powerbooks... Anyone else noticed this? I ordered mine online, and I was wondering if this is just a display model bug, or are they all like that? Should I cancel my order and buy an iBook instead? I love the size, but a sticky trackpad button would drive me crazy!
