1. Air Display

Ever wish you had an extra display for your Mac or Windows computer? There's an app for that! Air Display turns your iPad, iPhone, or iPod touch into a wireless display, to extend or mirror your computer screen.

FEATURES
Air Display not only gives you a wireless computer screen extender, but also works as a tablet input device. You can use your finger to draw directly on the screen's surface. Try it with a calculator, painting tool,
or music control surface! Simple gestures allow you to operate the right mouse button and scroll wheel.

Air Display's performance is extremely responsive, employing a unique dynamic compression algorithm. On a typical Wi-Fi network, mouse cursor refreshes are indistinguishable from a wired mouse.

On Mac OS X (and soon for Windows), if you have a Retina display, you can choose to operate at normal or double resolution. On Lion, you can even enable “HiDPI mode.” HiDPI, a built-in Mac OS X feature that renders UI elements at double resolution, is absolutely stunning on a Retina display.

Air Display works in both landscape and portrait configurations. Just rotate your screen, and it automatically reconfigures. When you rotate the screen, or disconnect and reconnect, your windows are automatically repositioned appropriately so you don't have to drag them back onto the Air Display screen.

You can connect to Air Display from both Mac and Windows. And because it's a universal app, it works on an iPad, iPhone, or iPod touch.

Air Display provides a virtual keyboard and mouse input on the iOS device. Air Display supports video-out to your TV or Monitor, either via Apple's AirPlay or with an appropriate adapter cable.

Some great uses for Air Display:
• General: Fill your Air Display screen with utility windows like Twitter, Facebook, email, or calendar.
• Graphic design: Make Photoshop and Illustrator usable on your laptop by putting your tool palettes on the iOS screen.
• Music: Use your iOS screen as a wireless control surface for Logic or Pro Tools.
• Programming: Use the extra display area for such auxiliary development tools as Console, Terminal, and the Debugger.
• Business: Move all of your iWork and Office palettes and inspector windows onto Air Display, and let your document fill the screen.
• Share: Use your iOS device's video adapter to share your screen on TVs, monitors and projectors in your boardroom or classroom.
• Amaze your friends by playing Flash animations on an iOS device!

On first launch, Air Display presents easy instructions for downloading and installing the companion Air Display Connect software for your desktop computer.

COMPATIBILITY

MAC OS X
To connect to a Mac, Air Display requires 10.6 (Snow Leopard) or later, on an Intel CPU. Both 32-Bit & 64-Bit systems are supported. (NOTE: On Lion, third-party video drivers, including Air Display’s, have some issues on these specific 15" and 17" MacBook Pro models: Late 2008 through Mid 2009, and Mid 2010. Please see avatron.com/lion for details and effective workarounds.)

WINDOWS
To connect to a Windows PC, Air Display requires Windows XP (32-bit only), or Vista or 7 (32-bit or 64-bit). Windows 7 Starter edition is not supported. (NOTE: Aero and DirectX will be disabled while connected to Air Display and re-enabled upon disconnection.)

3. Turntable.fm

turntable lets you play music together with your friends and other people online.  Each DJ takes a turn playing a song and the entire virtual room hears the song.  You can vote on whether the song is awesome or lame and if it receives too many lame votes, it gets skipped. 

turntable is also truly social.  You can chat with people in your room or fan your favorite DJs so that you can find them later.  Help people discover new great music or just sit around and listen to the best curated music experience online.

Here are some reviews of turntable

"The hottest new club isn’t in Los Angeles or New York. It’s on a Web site called Turntable.fm, where big-headed cartoon characters populate the D.J. booth." - NYTimes

"Listening to music has never been this fun. Turntable is also a great discovery tool since everyone is
curating all-the-songs-in-the-world to share the very best they’ve ever heard… with you. Oh, and do you remember chat rooms? They’re back. I haven’t used one since the 90s and now I’m non-stop chatting in these Turntable chat rooms and meeting people." - Techcrunch

"Turntable surpasses its competitors by luring users into a social context that is both gratifying and validating. In a simple chat window, conversations flow naturally." - NPR
