True, but you can't spruik that and then tell us in the next breath about the wonderful developer tools and Intellisense, etc., because most of that doesn't exist outside Windows. With Java it's not just the JVM that is cross platform - the whole developer ecosystem and culture is from the ground up. Every IDE, every compiler, every tool, all runs on every platform. It has it's holes, but largely Java actually achieves this, which when you need it, is a huge win.
Heh, I didn't even realise it was Australian slang. The meaning from your link is correct - to sell, extoll the virtues of or try to convince other people to buy something.
