Accustomed to Sony, I did not think much be satisfied with this product. Wifi connection (nagiateur web), zoom function, adjustable backlight acessible in a key opportunity to turn pages in touch or two keys (handy when zooming!), It's really a good product. Only downside: count 15 seconds to turn on and moves to the last page read. A small drawback does not prevent me from recommending this ... waiting for the next series!
