That's a good thing to mention especially for recent switchers to the Mac. Sometimes they don't realize that they have to copy the application from the mounted disk image over to the Applications folder and leave it running from the disk image which tends to cause problems with the app and sometimes the system. Always remember that for the most part, Mac app installations are as simple as dragging the application icon into Applications. The same goes for uninstalls....just drag the app to the Trash and empty it. Sure, you could go the extra mile and delete any preference files in ~/Library/Preferences (which holds the user preference for the app) or even in /Library/Preferences (which holds the app's global preferences).

While there are some apps that do come with installers, they aren't as common (especially since it's not the "Macintosh" way of doing things).
