You know, the funny thing is, I produce a half-hour public access cable TV show, and actually do the very things you mentioned. Regularly. Easily. All on my Windows box. True, I had to go out and get VideoWave and CoolEdit 2000 (now Adobe Auditions), but that set me back what, less than a hundred bucks? DVD burner for a Windows box? You can pick those up at Wal-Mart if you like. Most PCs now, even the ghetto-cheap ones, come with DVD burners in 'em. So from what I'm seeing, your list of features reads to me like the guy who paid too much for his Mac and is trying to justify it by listing out the stuff he'll likely never do with it.
I used to do that back in the 1970s and 80s. Of course, the equipment was far more primitive and expensive compared to the digital technology available now.
The point is that Macs are bundled with excellent software that is well-integrated and easy enough for the average home user - or public access cable TV producer - to operate successfully. Mac owners don't have to buy and install a bunch of extra equipment for video production, or digital photography, or digital music, or videoconferencing, etc. Macs are ready to do all of that stuff out-of-the-box, with no hassle.

Drop by sometime and I'll force you to watch my vacation DVDs. It's true that I don't use each and every application frequently - for example, I've only composed one song on Garage Band. Still, I'm glad Apple included several excellent apps with the Mac. It's fun to try them all, even if some get used more freqeuntly than others.
I've lost count of how many computers I've owned over the past thirty years, but Macs are definitely the best purchases I've made, and Windows PCs are the worst. Dollar-for-dollar, Macs are an excellent value, and they're actually a bargain for anyone whose time is valuable.
I used the Mac's Safari web browser, the built-in Apache web server and a text editor to create one, and posted it here. All you have to do is create a better one on your OS of choice, and post it on FR. And try to be original.
