p.s. and where goes the line between smaller projects ( Codeigniter ) and bigger projects ( Zend )[/quote]
I think you just answered your own question: it really is a grey area.

Zend is nice because there are many components which will make your life easier. It's also a little bit more mature (supports i8n natively, has a lot of good web-services classes, caching components, etc) as in that it's completely rewritten in PHP5 and thus uses a lot of 'smart' OOP to do the same things CI does but more elegant.

That doesn't mean CI can't do the same things Zend can. In fact because the way Zend components are used, you can easily implement them inside CI. The big drawback to me for Zend is that it's rather verbose: you need to write a lot of code to do small things. CI is much 'simpler'. You setup your database connection, and you are pretty much good to go. It's easy, has a very simple syntax which everyone should agree takes less than a week to 'master' and takes away a lot of the annoying repetitive coding.
