Screens is the best VNC (Virtual Network Computing) client you’ll use on your iPad. A graphical desktop sharing system, VNC lets you gain access to another computer remotely, including mouse and keyboard functions. After selecting a machine, and entering a password, you’re connected to your office as if you were there. Shortcut buttons let you execute common tasks such as minimizing a window, copy and paste, etc. The app also incorporates multitouch gestures. Screens isn’t cheap, but if you need VNC, it doesn’t get any better than this.
