"Nifty, though having used both languages I don't know why you would want to use Java instead of Objective-C." One big benefit of using Java is for people like me, who don't own a Mac, and can't develop using the Cocoa platform. Once I get my hands on a Mac, it probably will make more sense to use the native platform, but until then... I couldn't tell from the presentation whether some sort of JVM is required to be installed on the iPhone. It doesn't sound like it if the code is finally converted into Objective-C, but I remember seeing some installation instructions when I visited iphone4java.com... Or is this an entirely different project?
