PowerBook keyboard woes

Long ago, I wrote about my frustrations with the Fn key placement on my PowerBook. Someone has apprently been Googling around, found my entry, and then left a note that DoubleCommand has had some significant revisions since then and now allows you to reassign the Fn key! One more reason why I want a MacBook... I keep saying I'll just wait for the Meron based machines to come out and settle in a bit. I due hope that this next batch will resolve some of the heat issues that the first generation of apple-intel laptops.
