At Apple's iPad introduction, several third-party developers took the stage to show off modified and new apps. The iPad will run any of the apps that are currently available for the iPhone and iPod touch, but developers will be able to release customized software for the big screen and faster processor.

Mark Hickey from Gameloft demonstrated an iPad version of the company's Nova first-person shooter. Unlike the iPhone edition, gamers can reposition the floating directional controls on-screen. Players can also expand and reposition the game map, taking advantage of the screen size. The full version will ship later this year.

Travis Boatman demonstrated Need for Speed, a car racing game on the iPad. Again, since there's so much screen resolution for a handheld device, EA has experimented with adding a rear-view mirror, a shifter knob, and other extras. And like the iPhone 3GS, the iPad supports OpenGL ES, to accelerate graphics.

The New York Times rebuilt its iPhone app for the bigger screen. News stories follow more of a traditional print layout. But since you're browsing on a computer, they can include embedded videos and other multimedia features.

Steve Sprang demonstrated an iPad edition of Brushes, which will be available when the iPad is released. The finger-painting app will add new features, including playback to show the development of your art.

MLB At Bat will get a significant iPad update, integrating tap-savvy on-screen data with live game video. For example, you'll be able to tap a player to reveal his statistics, like a baseball card. Or you can pick from home and away announcers.

Apple is releasing the iPad software development kit today, so these app creators can begin working on updates. Apple hasn't yet announced iPad shipping details or a price.
