Last week I got the iCurve laptop stand for my PowerBook. While far from glamorous, ergonomically it's fantastic. It raises the entire laptop up around 6 inches, so the screen is significantly higher, and looking at it is more comfortable. I already had an external mouse, so I added an external keyboard and I'm all set. It's been infinitely more comfortable to work at my computer.

I have played with the idea of getting a desktop and a larger monitor, but my PowerBook's 15-inch display is adequate for now. In addition, I don't want to have to deal with file synchronization. Even well past its third birthday, my PowerBook (on OS 10.2.8) runs really smoothly and has been incredibly reliable for productivity in four states and two countries. The iCurve won't be featured in any interior design publications, but it's been an inexpensive, significant improvement in my working environment.
