Have you ever wondered why you can't simply author PDF files directly in a word processor? Most word processors like Microsoft Word use their own proprietary format, or a standard format like RTF. But Adobe's PDF format is the recognized standard in cross-platform page layout file formats; if you send someone a PDF file, you can be virtually guaranteed that they will be able to open and view it. And better yet, what they see will be exactly what you intended.

Though it may not seem like the world needs another word processor, the folks at PageHand decided that the ones that are currently available left something to be desired. And thus, PageHand, the word processor, was born.

PageHand has to be the most approachable word processor I've ever seen. When you first launch it, a sample document opens that is essentially a written tutorial. You are encouraged to change and edit the sample document as a way to get comfortable with PageHand's features, and can always revert back to the original sample document right from the Help menu item. With this tutorial, a new user could be comfortable navigating PageHand and using its various features very quickly.

TUAW previously covered PageHand prior to its release during WWDC, when they posted a first-look preview video. It's now in release, and is available for a limited time for $39.95, after which it will go back to the regular price of $49.95. There is a 30 day trial version available, and a money back guarantee.

While some modern browsers include built-in spell checkers, and some operating systems include built-in spelling and grammar checkers, there are people out there using operating systems and browsers that do not have these features.

If you're looking for some help with your writing and don't have access to Microsoft Word or a similarly-powered word processor, there is a solution available on the web called After the Deadline. The site (at the memorable URL polishmywriting.com) offers spelling and grammar help, and even writing style suggestions.
