My plan is to keep the App such that it only displays content based on the location, it's not intended to be a Wikipedia client. For the time being I'm not displaying the images, and I might keep it that way.

I don't know if I have much time to develop the App, but if I have I will most likely take it more towards and offline capabilities. So, the use case would be that at a hotel or some WiFi spot user could download the articles to the device before going to explore a city and if there is an interesting location user can check if there is an article on that location without a need of using data connection.
