Many iPad apps, especially office-style apps, are just desktop apps repurposed for the smaller screen. Tap & Edit (free) is different. It's a text entry and formatting app that incorporates gestures as an integral part of the app.
For example, a long double tap with two fingers selects a paragraph. Then you can make pinch and zoom style gestures to decrease and increase the font size. You can rotate the actual text using the same gestures typically used for rotating photos in other apps.
This presents a conundrum. It's great to be able to create stylish documents without resorting to a desktop computer. But how do you get those documents to other computers when you're done?
Fortunately, Tap & Edit lets you browse nearby devices and share via Wi-Fi, Dropbox, or email (HTML or PDF). I only wish I could upload directly to my blogging platform, but that is probably more of a limitation of blogging platforms, as they wouldn't know what to do with rotated text!
