Hope it gets packaged in the Debian and Fedora repositories soon...
I am coding Java 6 on Android, and its not fun once you tasted C# on the .NET framework.
Unfortunately, Java 7 isn't supported on Android, only in the very latest release 4.4 Kitkat.
I hope Java 8 will make Java feel more modern and nicer.
I would really like to see type interfering (the 'var' keyword in C#), and collection initializers.
