iPad App Store Reveals Launch Apps, Top Seller Lists, App Details

It's important to note that all prices and descriptions may not be final as developers can make adjustments to these items at any time. Wi-Fi models of Apple's iPad are scheduled to launch in the U.S. on April 3rd, with iPad-specific applications and services to go live on the same day.
