Handwriting App like PenUltimate for OS X

[markw10]

I have an iPad and use PenUltimate as a Handwriting Notetaking app.
My fiancee was going to get an iPad, especially for use with the iPad. When the MacBook Air came out she decided to get that instead.
She will use it a lot for typing but she's wondering if there's an OS X application that using the Magic Trackpad as a writing tool where she could take notes by handwriting with her finger on the magic trackpad. Is there anything like this?
Thank you for your help.

FWIW, click here and scroll down to Inkwell.

found in this (rather old) article.

Thank you. That should help but does it work with the internal trackpad or would I need something like a Wacom tablet?

the Apple article says:

Inkwell
Mac OS X comes with built-in handwriting recognition technology called Inkwell (or Ink). If you connect a graphics tablet to your Mac, you can write on the tablet using a stylus, and Inkwell translates what you write to typed words in your document.

you need a graphics tablet, me thinks
