It's ironic you mention the Mac since this particular notification and this particular implementation
are lifted directly from Growl on the Mac. You're correct. Mac's don't natively show any notification
for hardware changes. If you install Growl and the Hardware Growler on the Mac then you'll get
notifications for hardware changes. It's actually quite useful. It tells you when the wireless drops
signal, when you have a network drive disconnect unexpectedly and so forth.
