If I should decide to change from the 'soap bar' mouse that came with my new PowerMac to the Microsoft Blue 2-button, optical scroll mouse, is it as easy as just unplugging one and plugging in the other? I searched the apple.com site for 'hardware compatibility list', 'changing mice', etc, and didn't find anything useful. If anyone finds an Apple support article that's apropos, could you please indicate the search string you used so I can learn something? -- Thanks, Charles You might be a redneck if...
