I fully understand not liking the GUI. I have no problem with that, it's an understandable, reasonable complaint.
However, to respond to your more specific complaints:
You can maximize programs to fill the screen - that's what the green "+" button is for. I never use it 'cause I generally hate programs filling the whole screen unless there's good reason (like with Avid/Final Cut, or video games).
Yeah, the red X doesn't quit the program, it just closes the window. I, personally, highly prefer this to the Windows version, where you can't close the window without quitting the program - you can only minimize it.
And to properly quit, you either click on the program context menu > "Quit ___" or - my personal choice - Command+Q. (As I said before, keyboard shortcuts are the best thing ever, in any OS.)
there's really no task bar, it's just a bunch of fancy logos for software they assume you use. Can you even customize that thing? Where do you find out what programs are running? Task manager? Do macs even have one of those? Where do I find it because I would really like to know?
The Dock is 100% customizable. And it's super fucking easy to customize, too. You don't like seeing iTunes on your Dock when it isn't running? Drag it out of the Dock, it's gone. Want to put that new program you just installed onto the Dock? Go to the Applications folder, find it, and drag the application into the Dock.
Want to rearrange? Drag stuff around. Want it to be bigger or smaller? System Preferences > Dock. Want it to not do the "magnify" thing when you hover over it? System Preferences > Dock.
Want to know what programs are running? They have a blue dot underneath/next to them in the Dock. If it's a program you don't keep on the Dock, it will show up there when it starts running (with the blue dot), and will go away when you quit.
Task manager? If you're asking for a "Force Quit" window, i.e. a Mac equivalent to Ctrl+Alt+Del ... well, there is a "Force Quit" window, and you bring it up with Command+Option+Esc.
A more advanced Task Manager? Applications > Utilities > Activity Monitor. You can even put it on your Dock if you want - I have mine at the top, just in case I need it.
When you're doing high end video editing work like Adywan you have to go with a PC anyways, because I don't think even the most expensive Macs can handle that kind of work.
That is absolutely ridiculous. Of course Macs can handle "high end video editing." That's my job (as in, not a "fan editing" hobby), so I think I would know if Macs can do it.
And guess what? For more complex, "high-end" video/effects/CG work, I've found it to be much simpler to do on a Mac.
It seems to me that the majority of your complaints about Macs are unfounded, Windows-fanboy hearsay that have no basis in fact. I admit, some of your complaints are valid, but I could find equally valid complaints about Windows without resorting to "I hate it because I hear it can't do ______," even though it can do ______ very easily.
