This won't be on the topic of writing code but more on being personally-productive: I use my iPad to make hand drawn wireframes/mockups using Paper53. Going ahead and coding up an app without any idea of how the user experience/workflow goes blocks me up big time, on the flip-side wireframes/mockups multiply my productivity when the time comes that I actually type up code. For me, when I'm trying to do some small experiment or side project, rapidly drawing high-level mockups on tablets multiplies my productivity than spending time on Photoshop/Balsamiq.
