Your iPad decisions do not stop once you have developed on either the 3G iPad or the Wi-Fi-only model. There is also a not-trivial question of what apps warrant a space on your brand new mobile device.

App developers have not made the decision easy for you. The number of choices in the App hoard continues to scale upward, with developers now producing apps optimized to take advantage of the iPad’s features. Shortly after the iPad’s launch, Apple said that there were 3,500 iPad-optimized offerings in the App Store, and that number has only grown between then and now.

Over the past month, we have kept a close eye on the iPad-centric additions to the App Store both iPhone apps rationalized specifically to add iPad features or detached offerings designed solely for use on Apple’s new device. We searched across a wide spectrum of categories, from apps that help you get things done to offerings that keep you entertained. We paid special attention to apps that took advantage of the iPad’s unique features, most notably its expansive screen real estate.
