If you make excessive use of outlines, as Jeff Carlson does, you’ll appreciate the ability to build and edit them on the iPad. It’s often a more convenient method of jotting thoughts that can be expanded later on the Mac without having to pull out your laptop or wait until you’re back at your desk. In this review for Macworld, he touches on the advantages and depths of OmniOutliner for iPad, as well as a few surprising limitations. follow link
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
