Suppose you are writing a book with 15 chapters, and it takes a long time 
to compile your chapters. In LaTeX, you can include each chapter using 
\include {name of file} and then add a command \includeonly{a few 
chapters} on the top of your file. Only the chapters specified by 
\includeonly are included. So, it saves a lot of time in compiling the 
file. (I think there is also a command to exclude specific chapters).

It is roughly similar to compiling only a component of a big project in 
ConTeXt. However, I feel that the latex version works better since it 
maintains the numbering of chapters, etc.

For example, in latex if I include chapter 3 of a big book, its chapter 
number will be 3, and all the cross references to material outside that 
chapter will be correct.

In Context, if I compile the component containing chapter 3, its number 
will start from 1. I can get correct cross references by using 
\usereferences (and ignore the duplicate references warning), but the 
numbering of the compiled component is incorrect. This is one are where I 
wish context had better support.

Note that latex's method is not perfect. \include starts a new page, but 
that way it can ensure that the materical of included file is somewhat 
isolated with rest of the material. Context's \component does not start a 
new page, which is often times useful.
