my main issue with Android fragmentation is trying to support HTML5 Apps with PhoneGap/Cordova and various JS toolkits (Sencha Touch, JQueryMobile, Dojo). Each version(4.0, 4.1, 4.2, 4.3) has a slightly different version of the default browser and WebViewUI component(and don't get me started on Samsung devices which have their own issues regarding the default browser) with it's own quirks and rendering issues. They kinda fixed that in KitKat 4.4, using Chromium 30 as the basis of the WebViewUI component, but KitKat deployments in the wild are in the single digits.
