I just picked up a 17" powerbook 2 days ago to replace my stolen 15" TiBook. Although I had some reservations about it's size, now I wonder how I ever got along with a smaller screen. My only problem with the machine is it seems that the screen is sorta loose. What I mean is the screen travels rather freely with the smallest nudge. On the other hand the iBook I gave my mother had more resistance in the screen travel. Is this normal? Can I adjust this somehow? I don't like the feel. I would prefer to have more resistance. Something along the lines of the TiBook.
