Profcast
An interesting concept: Drop your Keynote or PowerPoint presentation onto the little application, begin your presentation, and Profcast times each slide and records what you say. When you’re done: poof! A podcast to upload to your server! I plan to try it with a wireless mic connected to my Mac soon.
Life2Go
I’ve used this program for years. It was called Pod2Go for a long time. This comprehensive solution for managing non-music content for your iPod rocks! It loads your iPod with news feeds, weather, movies, gas prices, driving directions, syncs your Safari bookmarks and Stickies, grabs lyrics, and manages a backup of your system too.
iPresent It
I haven’t used this but am including it here for my later exploration: According to the website, iPresent It creates slideshow images from any of your PowerPoint or PDF presentations and works with any iPod with a color screen. iPresent It saves presentations as sub-folders of a folder (such as the folder being used to sync to your iPod via iTunes). It easily updates your slideshows whenever you make changes to a presentation. Full drag and drop support for adding presentations.
You can easily remove slideshows when they are no longer needed. Removing them from iPresent It ensures they will be removed from your iPod the next time you sync. You can preview slides as they’re converted into a slideshow and also save presentations as albums in iPhoto. iPresent It will create slideshow images from any of your Keynote presentations.
CastAway
Full and comprehensive Podcast management. I’ve downloaded it but not really used it yet. I’ve not been pleased with iTunes’ Podcast management tool as I want to keep all of the podcast episodes in some of my podcast subscriptions but only keep the last few episodes in others. CastAway allows the user individualized subscription control. Cool!
