Here's a quick demonstration of two productivity apps,
Vlingo and Iris. Iris is modeled after Siri, the digital
personal assistant app for the iPhone 4S. I have very
limited experience with Siri, but every iPhone user I know
says it works nothing like they demonstrate on TV.
You'll see from the video that my preference is with Vlingo.
Although Vlingo doesn't talk back to you, it does execute
your commands much better than Iris (which is Siri
backwards). Clever? Not really.
