I've been looking for digital notebook capability for about a year. The iPad Mini + Noteshelf + Adonit Jot Pro is the best setup I've found to date.
I go from meeting to meeting with what I have in my hands, so the size and weight makes the Mini more desirable for me when compared to its larger sibling.
I'm happy to sacrifice the Retina display here for the desired functionality I need given the current display satisfies my needs just fine.
Pro's: Portability, easy to hold, perfect on the go notebook
Con's: Thin bezel may take some adjusting time, No HDR/Panoramic photo options (yet), only 5mp front Camera
