About the support for the hackers... hm... it probably depends on the definition of 'hacker', but there's MSDN, a HUGE resource for the developers on the Windows platforms, with references for all products, languages and tools, examples, knowledge base etc.
Speaking of installation, I guess it's a matter of preference. Personally, I prefer to download stuff that I need, burn the 'developer tools dvd', and install from there. apt, urpmi and similar tools are nice and I quite like their elegance and simplicity, but they are great when you have enough bandwidth and don't have to pay for the extra traffic, and not so nice if you have 3-4 machines to install or update.
And, finally, yes... hackers are few and far between, developers are a bit more common, and the rest are coders.
I didn't intend my comment to mean that Windows doesn't have legitimate hackers, I was just saying that it doesn't support them nearly as well as others do, with its closed API and licensed software-building tools. I was also poking fun at the "MILLIONS of hackers" comment, because in my opinion, there aren't millions of hackers in the entire world. I don't believe that hacker simply means "programmer", but rather, something a bit more. I certainly wouldn't consider myself to be one yet, even though I am quite confident in my programming skills.
So I'm sorry, I didn't mean to say that there aren't Windows hackers, just that I seriously doubt that there are millions of them.
