Once I got past the crashing (by re-installing, but they have supposedly fixed this in an update), I'm pretty happy with it.
Pros:
- Has a dimmer slider
- Saves notes, bookmarks, most recent page from all "nook"ish devices
- I actually liked their selection of fonts
- Support for Retina display
Cons:
- The font sizes are either too large or too small for me
- The dimmer is hidden behind a menu
- No clock in the upper menu when you tap the screen while reading.
