Pro Evenly-lit front display which can be turned completely off
Besides being able to use it in the dark, you can't tell where the LED lights are positioned, and that is a good thing since it won't oversaturate any area of it. Also, the display can be turned completely off to conserve battery, unlike the displays in some other brands and models.
Con No turn-key user experience
Icarus only sells the hardware, and they don't have a very polished app or bookstore, leaving the user to figure out which apps work without bugs(and some don't) and where to purchase/downloads the ebooks. Although it does support DRM enabled ebooks, the reader app has lots of older fonts, and changing them is not easy.
