Just a little while ago the NY Times officially released their iPad app. The App looks great and easy to read and the App is free right now. You can also read the entire paper free until early 2011 when the NY Times says they will start charging for access.
The app included all of the sections present in the print paper. With the iPad app you get exclusive videos that you can also find on the website but presented perfectly on your iPad. The app also includes push notifications for breaking news that will pop up when the app is closed. Check out the app at the link below.
