I have a Dell Inspiron 6400. It's actually a really nice laptop. It has an Intel Core Duo, and its resolution is 1680x1050.
For years, I've used various desktop backgrounds that were mostly gray. They all have something interesting to look at, but they all have very little color. In the past, I've had Apple notebooks, and I really liked the default blue Apple background; I find it quite comforting. I've tried to use the same background on a Dell, but for some reason it just irritates me.
I've had two theories about this. One is that the background doesn't match the color of the rest of the notebook. The other is that the Apple display is nicer. Well, I'm sure everyone already knows the answer.
Today, I held my Dell up to a big Dell cinema display being driven by a PowerBook. The difference was clear. Having seen them at the store, I wouldn't be surprised if the Apple cinema display was even nicer. It's depressing how faded my laptop looks.
So, as the title said, I'm missing my Mac display. I'll probably go back to using a grayish background.
