Keep in mind though, only the stock e-book app utilizes the page turn buttons, if you install 3rd party apps, they don’t work. People who commute to work on public transit often like this kind of hardware features. This allows you to hold it in one hand and easily turn pages. One of the other big selling points on the Obsidian is that there are two physical page turn keys. This is why I am very bullish about screens that are flush with the bezel, you absolutely get the best lighting system currently available. Additionally, most of these e-readers also suffer from a blueish hue to the screen. If you are in a very dark room and have the luminosity levels between 50% and 100% you will start to notice discoloration at the top and bottom of the screen. This is why the Nook Glowlight Plus, Kindle Paperwhite 2, Tolino Shine 1, Onyx Boox and Pocketbook products all have whats known as light spillage. It helps contain the light within a fixed area. I have found that the best front-lit displays have the screen flush with the bezel. Front-lit displays are hard to get right and many companies face huge challenges in order to give people a solid experience. Unlike a smartphone or tablet, the light does not emit from behind the screen, instead there are normally five LED lights built into the bottom or top of the bezel and project light upwards.
Many e-readers on the market have a front-lit display, which allows you to read in the dark. You have the ability to expand the internal storage up to 32 GB via the Micro SD. It has 512 MB of RAM and 8 GB of internal memory. Underneath the hood is a Dual-Core Cortex A9 1.0 GHz processor. There is a built in app store called Midiapolis, which has around a thousand apps. You are stuck with the built in digital bookstore that comes bundled with the device, whereas with the Obsidian, it runs Android. Sure the competition has better resolution, but they also lock you into their own walled gardens. The Kindle Voyage, Kindle Paperwhite 3, Tolino Shine 2 and the Kobo Aura H20 all have 1430 x 1080 and 300 PPI.
The resolution on the Obsidian is passable, but there are better products on the market if super high-definition displays mean a lot to you. I really like the fact the screen is completely flush with the bezel, the only other digital readers on the market that do the same thing is the Amazon Kindle Voyage the recently discontinued Kobo Aura. The Obsidian features a six inch e-Ink Carta Capacitive touchscreen display with a resolution of 1024 X 758 and 212 PPI. The Obsidian has a number of compelling things going for it, the screen is flush the bezel, you can install your own apps and it has an e-ink Carta display. The company has been selling other peoples e-ink devices for a very long time and decided to make their own. The Inkbook Obsidian is a new e-reader by Arta Tech, the former European distributor of Onyx Boox.
