Sony eReader PRS-600

The Sony eReader PRS-600 I got refurbished on Woot for $99 will accept "the following content files. Book: PDF file, EPUB file, Text file, RTF file, Word file (unsecured...if Microsoft Word is installed on your computer), BBeB Book."

It is a nice sturdy reader and the program Calibre can be used to convert many other file formats into the EPUB format.

I don't think the screen is very black and white except under strong light.
