Yes, I gave you the portability part, but in being so portable, JAVA programs lose alot of functionality. They're much slower than they would be if they were written in C, or even VB, first of all... Nothing OS specific can really be written into the programs, which brings up alot of compatibility issues... The interfaces are usually pretty crappy... Oh, and the worst thing of all, I can't use my dam scrolly mouse . I could go on.
I know you don't really think Java is a superior language, do you? Portability, yes. You can run a Java program on just about anything, but useability is where it is really lacking.

Oh, and I don't really see how C# has anything at all to do with Java. They may have pulled a few ideas from Java, but it's a totally different language, and doesn't suffer from the same shortcomings Java does. However, it's definately lacking on the portability side of things. (I think) C# programs only run on Windows, correct?
