I used their Easter-Sales offer (40% off regular prices) to upgrade my 9.03 Ultimate license
to the current 10.0x version, plus I took some time to play around with the updated
Python-plugin.
Usually I used plain-IDLE to experiment with simple Python scripts and classes - but
IntelliJ really makes a difference. For example, you can configure a missing docstring
to issue a warning (or hint, if you don't want to be offended...)
The editor feels just right and project support greatly benefits from its established
Java-brother.
Having one single IDE for both Java (ok, and Grails, Groovy and Griffon) and Python is worth the few bucks you need to invest in the Ultimate license...
