Perhaps the main issue lies with the relative inability to detect the presence of support: https://github.com/Modernizr/Modernizr/wiki/Undetectables https://github.com/Modernizr/Modernizr/wiki/Undetectables Android Gingerbread devices do not support it, and they are still the largest percentage of Android devices accessing Google Play: http://developer.android.com/about/dashboards/index.html http://developer.android.com/about/dashboards/index.html So it seems that a user agent detection and fallback for Android < 3.0 devices is still a great necessity, and it is difficult to say just how many other devices fall into this category. This next link is the most comprehensive list of support I could find, and although the support does seem widespread at this point, there are probably still too many user agent unknowns for someone wanting to make a mobile friendly library around the feature: http://caniuse.com/#feat=contenteditable http://caniuse.com/#feat=contenteditable
