I truly wish James Gosling the best in his new role at Google. I think it's wonderful that he was able to tell the world himself in his own blog. It is always a difficult for a high profile technology guru to position to choose who he will go with. I'm excited to see the innovations he will influence especially on the PC and network sides. In addition, he could improve Dalvik and slimline Java for Google hardware (such as their laptop project).
Sounds like good news. I hope he has ability at Google to help define the path of Android OS and to make it more in accord to the Java philosophy.
And considering his experience in server side development, it makes me think of the theme... "The network is the computer", perhaps Google will be taking mobile computing to a new networked level.
