t’s in magazines and newspapers. It’s on television and radio. It’s on buses and billboards and pretty much everywhere you look (except for Apple stores, where it’s likely still sold out). It’s the iPad! Selling three million units in the first 80 days, this hot new touchscreen tablet from Apple is a runaway hit.

Every iPhone and iPod Touch app developer looking to take the next step is moving into the iPad arena. Right now there are more than 200,000 apps in the App Store. With the iPad’s ability to run most of these existing apps without any modifications, iPad users have immediate access to a vast catalog of apps.

Although an existing iPhone app may run fine on the iPad, these unmodified apps provide an inferior user experience. iPhone apps pale in comparison to the sheer beauty and flexibility of native iPad apps. At the end of the day, iPhone and iPad are inherently different beasts, with different form factors and capabilities that encourage different usage patterns.

iPhone apps were designed for the iPhone, while the iPad should be treated as an entirely new platform with its own set of design requirements. Dave Wooldridge author of Apress’s latest book Beginning iPad Development for iPhone Developers: Mastering the iPad SDK provides three useful tips for all iPhone developers who want to leverage their skills to master the iPad-exclusive frameworks and features to create professional apps for the iPad:

1) Design app interfaces optimized for the iPad by taking advantage of the new UIKit features:
Popovers
Split View Controllers
Modal Views

2) Build powerful productivity solutions that utilize:
New graphics functionality
Core Text
Document Sharing
Advanced input methods

3) Take advantage of the iPad’s superior media capabilities with its new video and display options
