The Sharper Image Literati Wireless Reader
I bought this for myself and downloaded several books.  The wi-fi worked fine and I didn't have any trouble with it.  Then, after only a couple weeks, the reader wouldn't accept a charge anymore.  It's just completely dead.  I haven't been able to find any instructions on how to get the battery replaced.  I ended up going out and getting a Nook Color.  Needless to say, I'm very disappointed.  Had the battery held up, or I was able to at least get it replaced, I probably would have given it 4 stars.
