Your iPad can function as an extra wireless screen with Air Display. Last week the company announced that its PocketCloud products for iOS and Android have been downloaded over a million times. They can do it all -- provide remote access to a Mac or PC, let you edit documents and synchronize files, turn your tablet into a spare monitor, set you up to attend online meetings with colleagues, and even take dictation. You can take notes on the go, snap a photo of something cool, grab screenshots, or make a voice recording. Access files and run applications on remote Windows or Mac computers from anywhere on the planet.
