Lumia 920 with Stylus?

My girlfriend and I are up for new phones this month. We're both currently sporting first gen Windows Phones. I'm pretty set on the Lumia 920, but she's on the fence between it and the Galaxy Note II. What attracts her to the Note II is the stylus and the apps optimized for writing in notes.

I'm wondering if the Lumia 920 would work well with a 3rd party stylus, and if there are any Windows Phone note taking apps optimized for writing. Is there a way to use OneNote with writing?
