Of course, this was on some Sun marketing manager.'s blog. Clearly this guy has never used Java before. Let's get one thing straight here: Java ain't no speed demon.
Java is slow. Java is a memory hog (even more than Firefox!). Java hates your computer. The mere size of the Java download attests to how bloated it is. Even the first comment on that guy's blog is about how slow Java is. Amongst non-Java developers, "Java" means "brain damaged".
The really funny thing is the part where he's proud that 10,000 people are waiting for Java to load, multiple times, every day.
