I've been searching around the site, looking at the different types of coding, and come accross Assembly. This is one of the most complicating code ive seen yet and was just wondering what is it's most common use?

Assembly language is a very low level language.
It is very fast but very complex (therefore generally takes longer to write) and these days tends to be used where massive optimisation is required (a number-crunching algorithm) or in drivers and stuff where it has to interact directly with hardware.

This is completely wrong! Assembly language is very easy and can be used to develop any kind of application. Have a look at this article and visit the WinAsm Studio site for a lot of free open source tools written in Assembly.

The Space Shuttle's cockpit displays/keypad processors (an IBM SP0) were programmed in assembler as was its Heads Up Display(HUD) symbology processor (Hughs A10INS processor)
All of the kernel (and the vast majority of stock drivers and TSR's) for plain old DOS were written in assembler too.
True, it can be used to develop any kind of application, but what would be the point when a high or middle level language can do the job just as well (and more quickly)?
Assembly Language can produce small and very fast applications, no bloat, no dependencies (huge dll's), VERY easy to develop and above all, I can do anything I want without facing any HLL limitations.
Microsoft Macro Assembler (MASM), for example, looks VERY similar to C code and is no harder to learn. I would say that it is easier.

There is nothing wrong with the speed of today's optimising compilers. Entire operating systems are written in C, including both Windows and Linux - 95% of the source code anyway. What are the HLL limitations nowadays? Operating system API's are written with C in mind, and directly programming the hardware is out of the question in multi-tasking environments such as Windows and Linux.

No compiler can produce faster binaries than what assembly can do (written correctly offcourse)

still remains a 5%. why should I use C and assembly while I can be equally productive using assembly only.

Try to write a multithreaded application in VB6 or lower (I don't know about other versions, I never touched any), or a debugger, a large file edit control or ... You 'll fail. Try to use pointers with VB. You 'll be wasting your time (although it is possible).

You can call equally easily these API's with Assembly (and written correctly, the binary WILL be faster)

Although I don't usually do this kind of stuff, why not?
