Not sure about the negative reviews but for me the setup was very easy, less than 5 minutes. You can scan directly to your smartphone where the document, photo, etc. can be stored or emailed. The app will also access your photos which can be printed directly.
I also signed up for Epson connect, again less then five minutes, which will allow me to print anything on the printer from anywhere in the world where I can send an email. So now my printer has its own email address. Its a bit of a cumbersome email address, but during the set up process it sent me the email address so that I could add it to my contacts without having to remember it or risk making a typo.
I will update this review if something comes up later but so far its very good.
