Linux Bigity (er, Bigness!)
Whenever I use Linux I have the distinct impression that it's somehow bigger. I wasn't certain what was so big; maybe it was the fonts, maybe it was just the spaces between lines, but whatever it was, it felt suffocating. In Windows, I was used to having several windows open and only one or two of them dominating the screen real estate. But in Linux it always seems like there's less space available.
This is somewhat distressing to me because for the longest time I was annoyed about how much of my precious screen real estate Windows wasted! Whenever I install a new copy of Windows, I turned off all that stuff that uses extra space and yields minimal benefit, like the big "activity bar" on Explorer windows.
Well, Linux fonts are bigger, but I switched to MS Sans Serif and things were still pretty big.
Here are a couple of screen shots to illustrate. Consider the KDE "Appearance Box", which is comparable to the windows "Display Properties" box:

The KDE box is 279% of the size of the windows box (730x692 vs 404x448), and although the KDE dialog has more settings, you can see that the Windows dialog would be able to fit more stuff if it wanted to (though not a big list like in the Linux dialog.) The irksome thing about these KDE boxes is that their minimum size equals the size of the largest page. None of the pages use all available space effectively, and some of the pages require very little space indeed.
This is a bit of an extreme example, but there are others. For example, the KDE open/save boxes are significantly taller than the Windows ones when displaying the same number of rows.

It seems that virtually all dialog boxes in Linux space out their controls much more than in Windows; and many dialogs use space inefficiently. I spent good money on my 19" LCD; I don't want to use up space on, well, space.
