Just to give you a real world example, I installed CrossOver Office 4.01 into my Knoppix HD setup. I then used it to install Photoshop 7 into my Knoppix system, and I run PS7 flawlessly this way in Knoppix.

There are a lot of other Windows apps that you don't even need to install if you are dual booting Windows and Linux. For example both Windows Firefox 1.07 and 1.5 run pretty well under Knoppix via CrossOver Office when I simply click on the icons.
