I am glad it's not running Windows. I have the Archos 5IT and like how well Androids runs on it. I don't want to have to wait 30 seconds for something to boot up.
There are a couple of really good e-readers on Android (there could be more); 1. Aldiko,
www.aldiko.com/ and FReader,
www.readingsoft.com/freader.html.
As an added bonus the Android side should be a good comic reader.
