My first ereader. Initial impression is quite favorable. Got this as opposed to Kindle since it had a memory card and most of my ereading is pdf files of public domain literature found on web. Web reviews also very favorable as for Kindle. Additionally, the built in reading light was a significant selling point as it extends readability conditions. As to the screen lighting, it is childishly simple - just a row of 8 led lights across the top. Works OK; but, is clearly just top lighting spilling down across screen.
