i own a gen3 since a few month and it has really change my way of reading.
finally i got the impression to 'read'. after 20 chapter of naruto, so far i only see the problem of the folders, but even with that you can put your picture on sd card and make free space by taking it out. or also create folders and then select 'sort' 'file path' to get an easy of reading your manga in your order of preference.
