Today's Amazon Appstore deal is quite the bargain, and its value speaks for itself. Jump Desktop isn't the only remote desktop client out there, but it has no shortage of features. The app supports both RDP and VNC protocols, so if you have either already configured on your PC, you're good to go. Jump Desktop does not require that you install additional software on your machine. Awesome? Awesome.
The app allows you to control your computer as though it were a tablet, with pinch-zoom and two finger scrolling both supported.
