Does IntelliJ Ultimate include everything that Astella has? My basic question is if I already have a license for IntelliJ do I need Astella too?
I assume that, at the moment, IntelliJ includes eveything in Astella, with the profiler and UI designer available as separate plugins.
The mean idea is to offer a cheaper, more focused package, similar to RubyMine or PhpStorm (which are still available for the "flagship" IntelliJ product as separate plugins).
Please find answers at http://confluence.jetbrains.net/display/AS/Astella+FAQ. Astella package includes Perforce integration.
