I was all set on getting a PB 15" since I mostly use my Toshiba notebook at home and gave away my desktop PC. But ever since I started using my notebook as my sole computer at home I've noticed that my neck is sore all the time. I realized it's because when you use a notebook you're always looking down at the screen and cannot have the screen at eye level...otherwise the keyboard is too high. It's that problem inherent in a notebook because you have screen and keyboard in a fixed proximity to each other. The ideal keyboard position is to allow your arms to hand down by your sides and elbows bent at a 90 degree angle. This postion puts the screen much too low so your head is always titled down. The solution I guess is to get an iMac. I don't really need the portability of the PB but I kind of like being able to move it around and use it while watching TV by putting in on a little TV tray I eat off of sometimes. As we get older these aches and pains just don't go away and I think I'd be better off getting the iMac.
