The problem is not to know what platform is better for mass public/business/geek... But how many times a company or a single developer will have to fully re-write their applications instead of just "porting".

GNU platform is a great success because it runs on almost all hardware/operating system from the same POSIX C source code. Small directives and compilation chain switches do the job !

Mobile market is so volatile that it is still war-time to define the "standards".

At the moment, to target as many users as possible, an application must be written in JavaME for old/new Symbian versions, in ObjectiveC/Cocoa for iOS iPhone, in Java/Dalvik for Android (or POSIX C for Linux), and Qt/C++ for new MeeGo/Symbian. [what about Samsung Bada ?]

Well, far enough, it is too much work (first dev, tests, fixes and maintenance to keep up-to-date !) and requires so many different competences, some targets are simply excluded. Hope comes from cross-compiling or porting required virtual machine.

For me, cross-compiling requires too much work, potentially on each application (at least if sources are available). Porting the VM is done once for all, applications run as soon as the used APIs are available.

I have started the job but I lack knowledge about Android build system and its specific sub-systems.

For those who want to help, you're welcome: first get android or android-x86 sources from Git and follow my track to get it compiled for your Linux or ChromeOS.
