[TYPO3-english] FLUIDTEMPLATE partials

[Victor Livakovsky]

Hi, list.

I'm now learning benefits of FLUIDTEMPLATE and would like to use it in my 
next project to feel the difference between it and usual TEMPLATE or TV.

So far so good, but I can't get the meaning of partials concept. What are 
they used for? Examples across the internet don't tell much: some use them 
for logo, some for menu - but these tasks may be easily and even better 
achieved with normal TS.
Can, someone, please, tell me, what is the benefit of placing:
<f:render partial="Logo" />
instead of:
<f:cObject typoscriptObjectPath="lib.logo" />
Or, maybe, I understand wrong the meaning of partials?

And another question: as I understand, FLUIDTEMPLATE still can't provide 
some analog of FCEs, as TV does?

Thank you for your answers in advance.
