Sidetrack. Drives me insane using a Mac laptop without it, as I use the scroll function on the right edge of mine.

Never really found the need to map a button as a right click, since I can Ctrl-click decently now. Though any time my Powerbook is at a desk, it has a mouse and second monitor attached.

That brings me to my Powerbook gripe. The lack of a right click button is nothing compared to my desire for a dock/port replicator solution from Apple. IE, a special port on the laptop built for such a device, and not third party jobs that are just as much work to attach as plugging in each cable.
