Setting OSX to quit programs by pressing X

Yes thanks for that oh protector of the cats. Something that makes life easier is a good idea in any program even the blessed OS.
Surely people must get sick of having to go back quit everything thats open. It takes two clicks when one would suffice

If you want to close a program without closing it surely thats what minimize is for so why the redundant button.
Heres an idea if theres anyone working for apple how about a forth button that quits the application. Current users will be so used to not using it they will have time to get used to it.
More than one click to do a constant task is one click too many

My word you sound like an old man saying that’s the way it's always been and we're ****** if we are going to change.
I have a word for you it's called progress.
None of these solutions are quicker than clicking one button.
The Pc way is just about everything you do is customizable. That way things run the way you want. After all is it better things work the way someone else wants it to work or the way you want it to work.
OS is a very good operating system but what lets it down is there is very little room for customization. If I want to set the x button to quit an application why not give me the user the ability.
It's all about control. Big companies want you to do it their way so it's too difficult to move elsewhere. Multitasking should not create more work to clean up, it should streamline a workflow. It's like pulling out a load of folders from a filling cabinet thinking, I'll have a lot of tidying to do when this is done. Or I wish I could move on to this big task but I have to tidy up before I start that.
Since getting involve in apple products I have come to realize that Apple is the new Microsoft. That’s one of the reasons we are going to see more viruses for the mac, cause programmers hate controllers.
DRM I rest my case.

I have come to realize a lot of Mac users are people with nothing better to do with their time than trawl forums being unhelpful. Have you nothing better to do with your time. The point of this forum is to help each other with problems not waste peoples time making stupid diggs. How about I use my macbook to do what I want.
I work in IT and bought the MBP to learn a bit more about OS as every now and again a business has a Mac in the office they want added to the network. As it stands I have grown to quite like OSX so I'd like to know more. As for how it compares to Windows well Microsoft has a massive problem that the mac doesn't have to deal with - Viruses. Computing on either OS would be child's play if security did not have to be such a big factor so windows has a lot more to do. This is why OSX is so streamlined and relaxed. In a number of years this will change and you will see your precious evolve into an armored tank that is cumbersome. This is due to the fact OS is selling more so the hackers will eventually see it as a worthwhile project. Each new version of windows brings a higher level of required security and thats what the majority of MS programmers spend their time working on. Not flashy streamlining.
I have things I love and hate about both Operating systems but neither is far from perfect. So I would like to have the option of customization, hence I wasted my time asking you fine people.
Lastly i do a lot of music. So the requirements I have from the system in line with how long is a piece string so the less apps drawing on system resources the more tracks/instruments I can add to a song so you can't just state we don't need to close apps as the memory management is sooooo good.
Anyway who is this 'we' you keep referring to like you are a single entity. Don't use the word we unless saying I am a wee bit irritating.
Anyone out there want help your help would be appreciated.
