I just downloaded Word Wars, a Boggle-like word game, on my Galaxy Nexus, but I didn’t use the Google Play store. Instead, I browsed to the Firefox Marketplace on the mobile version of the Firefox browser. It installed on my device quickly, and Firefox even created a separate icon to launch the app on my homescreen.
Yep, pretty easy, huh? Build an app, distribute it on the Firefox Marketplace and distribute across Android and FirefoxOS.
This is the web ending fragmentation.
