One of the hazards of working @ home is the tendancy to get a bit lonely. Without office mates, you may find yourself going a bit stir crazy. I initially downloaded the TWiT app (see links below) because I'm turning into a bigger geek every day and I really enjoy the programming provided by Leo Laporte and friends. Whether they are discussing technology, the law, current events, science, or photography, the conversations are insightful, fresh, funny and always chock full of wonderful information. I frequently listen at my desk while working, but have found the app wonderful for using on my mobile appliances, especially while doing mundane housework chores.
One of the unexpected benefits of the TWiT apps is the sense of community afforded by the apps. The official app provides access to the chat features. Enter it and you'll find fun commentary, ready answers, and a sense of humor that's unique to geeks and those who love them.
I've used both the official TWiT apps and the ones by Mediafly. For the iPad, I'll admit to preferring the Mediafly app, since the app is not yet optimized for iPad. The Mediafly apps do not offer access to the chat features. Both provide not only live programming access, but also archived programming in both audio and video formats.
