BlackBerry: If you like puzzle games and own a BlackBerry then be sure to try out Crazysoft Paintball II. Your goal is to join three or more balls of the same colour and ensure they are next to a pipe. Once in place, you select them then splat them with paint using the action key. The balls will then change colour and get sucked into the pipe, leaving more space on the board for you to make your next batch.

Windows: If you'd like to use the extensive iTunes library on your home PC while you're somewhere else, you can either carry your entire music collection with you or simply use pulpTunes. This easy tool lets you remotely access your iTunes library via a web browser, and listen to your favorite music wherever you are.

Mac: With broadband speeds and processing power increasing all the time, desktop sharing is becoming an increasingly competitive area in the software field. Mikogo has been available on Windows for well over a year but only now has it finally been released for Mac. It's a free, simple and extremely easy to use application that allows you to switch from host to presenter in a click.
