IMO, the screen (15.2" widescreen) is not big enough to warrant a higher resolution. The poblem with some Dell systems is that the resolution becomes unusable for practical purposes. For fonts, you end up having to increase the default size of all text, next are window elements. Mac OS X doesn't have a nice global configuration to adjust the DPI of the desktop elements, so this would be even worse on a Mac.

The hardware features, build and ergonomics put the PowerBook far ahead of any Windows machine I could find. Funny as it is, I found some second tier manufacturers, like Acer, Asus and eMachines, to offer far better machines than Dell or Toshiba. Some of the newer IBM systems aren't bad, but none of the big PC names seem to know anything about physically constructing a portable. Every system looks like it was pieced together in an afternoon by parts delivered from 20 other departments that didn't communicate with each other.

If you plan to use the notebook at a desk station, then your external connection options with the PowerBook are also much better than any PC-based model. DVI-I output (that's digital or analog (with adapter) on a single connector) with support for pretty much any standard panel around (extended desktop, sole desktop or mirrored).
