I did a little leg work on the subject of two finger right clicking on powerbooks. I E-mailed the person over at Side-Track and inquired as to why he didn't develop a "two finger right click" option and "two finger scrolling" for Side-track(http://www.ragingmenace.com/index.html). The answer he gave me was interesting. He said that it would be vary easy to add two finger right clicking. I assumed this would be easy because he already designed a USB track pad driver from scratch for the powerbooks. Unfortunately he is unable to release such a feature because apple holds a patten on the IMPLEMENTATION of "two finger right clicking" for the non open source USB track pad drivers. The jerks at apple aren't releasing a two finger right click option for the powerbooks on purpose. They know they can use that feature restriction to coerce people to buy MBPs.
