I'm looking for an ereader that can easily sync content with a laptop. It should function similar to dropbox: copy a PDF in a folder, and it should upload automatically to the ereader - if wifi is connected of course. So connecting a USB cable is not an option.
Currently I have a Sony PRS T3 ereader, and I'm very fond of it. Only problem is that it's such a hassle to copy files to it.
I wonder if Amazon or Kobo have solved this problem, and how it works out. The reader should be an e-ink reader, not a Kindle Fire with Android.
