Developing a multilingual site in the autumn of Drupal 7, I am inclined to use entity translation all the way.
Drupal core comes with content translation. If I have both enabled, I am having a confusing user experience while editing content. I disabled content translations (and some modules that required it), and entity translation still seems to work and everything makes more sense. So tempted to keep it that way.
However .. I just disabled a core module. Is that ok?
