Shai Almog worked at Sun on Mobile JVMs just as phones started to turn from phones into something else.     Sun had deep expertise in mobile development, and amazing engineering driven culture and relationships with manufacturers and operators. And yet interal politics and the collapse of its server market made it hard to get things done.    At Sun, as the mobile market changed, Shai and his friend Chen Fishbein launched a popular UI toolkit.       Today Shai shares their struggles at Sun and after it to shape mobile UI development.
