Got an hour this weekend? Why don't you master the Drafts app? I did an entire series of screencasts on Drafts and it is a really handy app. Drafts let's you quickly capture text on your iPhone and iPad and then perform actions on that text with just a tap. There is nothing else like it and Drafts replaced the paper and pencil I used to always carry in my pocket. Anyway, below is the introductory video and you'll find the rest of the series (15 videos!) at the Drafts website. It's like getting a MacSparky Video Field Guide for free.
