Last January, when Steve Jobs introduced Keynote and iDVD 3 at the Macworld keynote, I wrote about how bored I was when he spent what seemed an interminable amount of time showing off the new themes in the two programs.

Flash forward five months: Yesterday, for the first time I used Keynote and iDVD 3. And what have I spent nearly every free moment on the Mac doing? That’s right: playing with themes. And showing them to anyone in range.

It turns out Steve was right, after all. Themes are cool.
