No, #2 is about the repository slicing, branching, merging (SCM in other words). 
Let's suppose I have the product that have 2 directories: component1 and 
component2. They were developing together for  previous product (on the same 
branch, for example). Now, I would like to have component1 and replace 
component2 with some 3rd party component. What should I do with Git to get this? 
Or maybe I wish to stick with some version of component2 and provide only bug 
fixes for this product...
Or let's take a look at GDB. They are using binutils which are in separate 
repository (they use CVS, but let's imagine they use Git). How many effors they 
will need for SCM? For example, they would prefer to stick to some stable 
version/branch of the binutils but should be able to commit bug fixes.

Once again, perhaps there is some way to do this with Git? I did not yet find 
it.

oh, yes, since we have big drives and fast internet, we do not have to worry 
about space and download time... :-)

This probably true. Thought I did not have a lot of problems with it unless I 
use GUI.

yes. I did not yet noticed any performance problems with Git on windows, except 
a sync/download time (for android, mostly)
