3 tips on windows
Turn your computer into alarm clock
If you are running windows you can use your computer as an alarm clock which will start playing music on the selected time.
To do that, go to 'scheduled task' window (accessories -> system tools), add a new scheduled task, and when prompted to select the program to run, select instead an mp3 song or a playlist you'd like to be played. Then just select the time and you're all set!
Zoom in/out with the mouse wheel
You can zoom in/out in almost every Windows application by holding down the control button and scrolling the mouse wheel up and down.

Always 'safely remove' your USB drive
After you're done working with your disk-on-key, if you're using Windows, always use the 'safely remove hardware' wizard.
If you fail to do so you may loose all your data on the disk - especially if you've just finished writing on it.
