Sun Is Porting Java To the iPhone
krquet notes an InfoWorld article on Sun's plans for the iPhone. After studying Apple's newly released SDK docs for 24 hours, Sun decided it was feasible to develop a JVM, based on Java Micro Edition, for both the iPhone and the iTouch. An analyst is quoted: "I think going forward, with the SDK, it takes out of Apple's control which applications are 'right' for the iPhone." The article doesn't speculate on how Apple might to react to such a loss of control. "Apple had not shown interest in enabling Java to run on the iPhone, but Sun plans to step in and do the job itself... The free JVM would be made available via Apple's App Store marketplace for third-party applications."
...third-party apps can't run as a background process? From the documentation: "Only one iPhone application can run at a time, and third-party applications never run in the background." Limited resources or not, it seems like this is going to end up like the older versions of PalmOS.
Trust me, no Java app on OS X feels anything like a Mac app. They look slightly better than on Windows, but they still feel like Java.
