difference between crystal enterprise and business objects enterprise

[mirage10]

Hi,
Can some one direct me to any website which tells us about the difference between
crystal enterprise and business objects enterprise

i see that web intelligence,universes are there only in business objects and not in crystal enterprise.
Business views are a special feature of crystal enterprise.

I want to know what features are unique to crystal enterprise/business objects.
currently we have crystal version 8.
first of all i want to know what benefits we will have if we upgrade to an enterprise version rather than having a standard edition.
if we purchased business objects enterprise do we also get crystal enterprise in the package or is it completely different.
i am sure this information should be somewhere in business objects website,but there is so much information i cant seem to get the right answer.
any input will be appreciated.
thanks
