Best Productivity/Entertainment apps for iPad?

The most productive and free app that I have on my iPad is Notes. All of the other apps are games unless Twitter can be considered as a productive app.

I like abc's app cause of modern family and besides the video overlay not responding to my touch input sometimes it's a pretty good app.

I like GoodReader for reading and filing PDFs, Things for getting things done and OmniGraffle for making complex ideas visual.

• The Cozi Family Organizer is the newest way to sign in to your Cozi account while you're on the go. Effortlessly manage your family calendar, shopping lists, and to do lists, and keep your family journal updated with special moments and photos—all on your iPhone or iPod Touch. If you've used Cozi Mobile, you'll appreciate the improved performance and additional features available on the new ad-free Cozi iPhone app. (iPod Touch users: the family calendar is not yet available offline; requires an Internet connection.)

• Evernote for iPad & iPhone lets you make new text and audio notes, as well as view your existing Evernote content all with a swipe or tap of your finger.

• Dragon Dictation is an easy-to-use voice recognition application powered by Dragon NaturallySpeaking that allows you to easily speak and instantly see your text content for everything from email messages to blog posts on your iPad™, iPhone™ or iPod touch™. In fact, it’s up to five (5) times faster than typing on the keyboard.
