Ah, Greg Reinacker has sent me the Java quote I mentioned before..it was in fact he who said:

"1. I personally believe you can write performant, scalable systems with either Java/J2EE or .NET.  It's all a matter of good design.  And I certainly didn't mean to sound like election coverage!
2. Most ".NET people" I know also believe that you can certainly write good, scalable systems with Java/J2EE.  In contrast, many "Java people" don't believe that .NET is even worth considering.  And it doesn't seem to be based on technology - it seems to be fear of Microsoft.  Here's a great example.  Yikes.  Can't we all just get along?  (this is a part of why I've spent so much time working with web services.)"  [Greg Reinacker's Weblog]
