Solutions to Present Complex Information on a Small Screen

Mobile interface designers have a challenging job. They deal with increases in speed and information density, when they are stuck with the same little screen and resolution they had two or three years ago? In Zooming in on Legibility Mark Frauenfelder mentions 2 current solutions:

• Collapse-to-zoom: allows users to use their stylus to draw lines across areas on a thumbnail display of a Web page to either zoom into desired content or collapse unwanted content.
