The InkBook Prime by Arta Tech has a number of advanced features that allow you freedom to heavily customize the device. You can turn off the touchscreen completely, so you can exclusively rely on on the physical page turn buttons. The Prime also has a high contrast mode, which turns the text white and the background black. This is tremendously useful if you are reading at night and using the front-lit display.
If you are wondering how you can disable the touchscreen or use nighttime reading mode, we have produced a number of videos that teach you how to do it.
