I've recently downloaded the Eclipse IDE for Java EE developers (for web apps development). Does it make sense to delete my "regular" Eclipse IDE for Java developers? I mean, is there a feature in the regular IDE which isn't included in the EE IDE?
(I also use eclipse for Python programming with the Pydev plugin)
The different "editions" of the eclipse IDE are basically just a different set of plugins on top of the basic eclipse platform. So if anything is missing you can alyways install those plugins when you need them.
Yes it is a super-set. Also, have you tried NetBeans? It has better GUI, better javadoc support and it is way cooler to use! (and free)
Not everyone needs the EE tools (mainly WTP - web tools platform); they may only be doing client apps or writing eclipse plugins.
