Yah... right...

"The world is down to two developer camps: One is .Net, the other is Sun ONE Java. Java is the No. 1 development platform. Viruses are a feature in .Net, but Java has security built in. I find it funny how the default setting in Win XP lets in Office macros but blocks Java," he told an amused audience.

"Sun ONE runs on every system and processor," the CEO said. ".Net runs only on Windows. It’s mankind versus Microsoft. .Net is a joke."

I agree with Drew on this one. Definately FUD. I hate to point out the obvious, but...

1) Viruses in .NET? What? I'd like to see where he got that one...
2) Since when has Java been the No. 1 development platform? Windows has been the number 1 development platform for many, many years thanks to VB and VC++.
3) Neither XP or Office are built on .NET...so I don't know where the connection comes there.
4) The default setting in XP doesn't block Java, you just have to install it...just like the default setting in XP doesn't include Office either, you have to install it.
5) Sun ONE does not run on EVERY system and processor. Their app server only supports Windows, Solaris and Linux just like the rest of their crap. Yah, you could theoretically run Java on any platform as long as some other company has implemented the Java runtime on it, but the same is true of .NET. As far as consuming web services are concerned, maybe the problem is that McNealy and the rest of Sun have yet to realize that they are a platform agnostic way of sharing data whether they are made with .NET, Java, Cobol, or PHP.
6) .NET does not run only on Windows. (Mono, Rotor, etc.)
