I seriously love my iPhone.
More importantly, I love the way it allows me to work.
Currently I'm beta testing a new version of the Movie Slate app (along with a few other apps) and am loving the features that are now making it easy for me to do my job. Another few apps I'm playing with are Cinemek's "Storyboard Composer" and "ProPrompter from Bodelin. These apps are going to improve my video tutorials and very soon my filmmaking... I'm really getting excited about doing some more narrative work and I feel like the iPhone has fueled that.
Stay tuned, because I'll be writing about all of these very soon.
