Trashy article. FAIL!
Any discussion of Java should separate out the language from the VM.
This article fails to do so, so immediately makes it bogus.
However, if he wants to poke fun at the VM, he should remember that the VM runs countless backend applications like Jira and Confluence (fantastic products) and modified VMs run Google Appengine alongside python.
If he wants to write about how the Java VM failed to be productive inside the browser, he can write an article about that... but that's not an argument about Java.. and really demonstrates the failure of Sun.. A knowledgeable sysadmin should know better...
