This book turned out to have some solid information on figuring out the designing and packaging concepts you need to keep in mind when setting up an appliction for a tiny screen hand held device. Forget complex rich-media site artwork that makes people linger on a widescreen monitor and think focused task operated by thumbs. Reminds me of the efficiency principles from the days of 3278's and VT100's in a way ... there's not a lot of room for noise factor on a screen the size of a playing card. The book emphasizes this and shows a number of good examples. The section on style guide planning the top, middle and bottom sections of a display page was worth the price of the book.
