Hi,
I hope you know that Crystal enterprise is distributing reports through web. Though this feature (distributing reports through web) was there with CR8 and CR8.5 it uses only WCS (Web Component Server).
Where as CE comes with many more server components for specific tasks like Page Server, Cache Server, Automatic Process Server etc., These components are not available with CR
Secondly, there are two editions of CE (now from CR9, there a three editions) like Standard and Professional. What comes free with CR is CE Standard edition, which has got its own limitations. Of course, you can use it for developing and testing. However, for commercial deployment, you must go for CE Professional for which YOU HAVE TO PAY!!!
