Grainy ink rendering, crashy
Ive used better pen and paper apps, by far. (Penultimate comes to mind.) Ink rendering is jagged and pixelated. The default pen sizes are way too small for an iPad. Exiting the Help menu crashes the program. The ink does keep up with my stylus fairly well, but it cant save it from painfully bad text rendering and, as others have noted, terrible palm detection.
