So yes. I'm currently writing this post from my iPhone and from the comfort of a place most people sit to use their smart phones on their 'Angry Bird Breaks.' I believe they coined another term for this... It's a functional app that I'm still really exploring all it can do (which probably isn't all that much) but at least it's semi useful for instant, on the go posts.
You can also attach images, as you can see from the photo I took of the lovely ceramic waste bins in Suzhou, China. Possibly the nicest looking garbage bins I've laid eyes on.
