The New York Times has replaced its limited "Editor's Choice" iPad app with a new version that provides the newspaper's full content, pending the user's (free) registration. The app will be free for users until "early 2011."
Unlike Editor's Choice, the new version (simply called NYTimes for iPad) includes articles from every section of the publication. You can navigate each via a pop-up list. Select any one to read the related articles.
You'll notice that a banner pops up prompting you to register. The process is as simple as entering a username and a password, and will push you out of the app and into Safari to finish the process. Once complete, you must click a ink in a confirmation email. The next time you launch the app, the banners will be gone.
