If you are carrying a Tablet PC or any other computer with a touch-screen, check out InTouch – it’s a cross platform desktop client that will let you interact with your Facebook stream using simple pen gestures or touch input from your fingers.
With InTouch, you can post images to your Facebook profile, tag friends in photos, publish web links (including YouTube videos) on to your Facebook stream by simply dragging and dropping content from the browser or your desktop into the software window.
InTouch is primarily designed for Wacom tablets but you can run it on any Windows, Mac or Linux machine as long as it has Adobe AIR.
