Utter nonsense.

The Sony website does not say that their PRS505 does not have a search function which is a major issue for me. But I did my research first and ruled it out. Neither does Sony mention that you can't read books bought from either Amazon, meant for the Kindle, or from eReader. Does all this mean Sony is lying or is deceptive? No, of course not. Bottom line: manufacturers don't have to tell you what their products don't do.

That said, I do prefer the way Sony lists their supported formats to Ectaco's.

My advice? Do your homework.
