With Linux being used as the foundation for numerous smartphone and mobile internet devices, it is tempting to suggest that this movement is going to open the doorway to desktop Linux. Tempting, but not accurate. Linux, the kernel and its immediate subsystems, has never been healthier and its openness has made it relatively easy for developers and manufacturers to get an operating system onto a new class of mobile devices. However, consider the two leading strains of mobile Linux; Android and Moblin. Both start with Linux at the core, but if you move up to the user interface, they diverge.
