Why not? We could stay updated and and have everything we need rather than constantly going to EMC website and see the "Full Website Version" But it's all in a application.
It's a great idea, however, not very practical. The developers would have no time to develop or maintain it. Staff has said that themselves. However, jkrmnj has made an app: http://empireminecraft.com/threads/emc-android-app.39404/

I have been working on an Android app that Penguin linked above me. The app has everything you will need for casually browsing the forums. If you have any programming knowledge, you can contribute to the app to make it better.
We do have RSS feeds of Empire News and Empire Updates, (click the orange icon on the forum index) Anyone could design an app that checks these feeds, and posts an alert on the device when a new entry is posted. Doesn't have to be done by us
