Leopard's new screen-sharing feature is handy for remote troubleshooting, but what about checking on things when you're not at your computer? No problem: with free Mocha VNC Lite, you can view and interact with your Mac (or PC) anywhere you've got your iPhone. Mocha VNC Lite works in both portrait and landscape orientations, and you can pinch to zoom in and out of the remote screen. It also lets you store up to six computers as shortcuts so you don't have to key in server information every time.
