One of the most frustrating parts about working from the road is not having access to the files on your office computer. Remote access software lets you tap into your desktop remotely and open and edit files, check e-mail, and even spy on colleagues using a Webcam. LogMeIn Free has a key advantage: It can be downloaded to a Mac. For features like desktop sharing and file syncing, however, you will need to upgrade to LogMeIn Pro ($249 per year for five PCs). LogMeIn Free works with Windows Mobile smartphones, and the LogMeIn Ignition application ($29.99) lets you use it from an iPhone as well.
