The issue is pretty much the same as it ever was -- hardware manufacturers support Windows first. Linux is usually later if at all. Community support sometimes steps in to fill in the gap, and some manufacturers (most notably AMD) are coming around, but this is still usually the issue.

Oddly enough, this means that Linux tends to work better as the computer it's running on gets older. The reverse is true for Windows -- updates tend to make it slower and/or have more compatibility issues. A computer that worked better with Windows a few years ago will not-infrequently perform better under Ubuntu today. It's not usually suggested on new PCs unless it's spec'd specifically with Linux compatibility in mind.
