The failure of J2ME has nothing to do with your particular preference for non-Java UIs. J2ME was a creature of the early 2000s. JSR-88 ( the J2ME spec ) was a done deal by early 2003. Implementations & maintenance releases rolled out over 2003-2007. In contrast, Android 1.0 was released in Sep 2008. All of the success stories of Android, the apps & suchlike, are the post-2010 timeframe. Notwithstanding the experience of hindsight, you had a decade between J2ME & Android, which is like a light year in tech timeframe. Nobody could imagine billions of consumers buying mobile apps in app stores back in 2000. Today that's a reality. To attribute change in customer behavior solely to Android being better than J2ME is quite bizarre. Today, Android is an order of magnitude better than J2ME. But when it debuted, J2ME was infinitely better than anything out there because there was practically nothing else. The remarkable Android UI experience is due to => Scott Chase and Romain Guy => The same Swing gurus who wrote the crappy Java Swing UIs that made you puke :)
