I've just been playing around with PyCharm and so far I'm really impressed. The only thing I see missing is the ability to turn off anti-aliasing on the fonts (I find coding with aliased fonts hard on the eyes).
I had the same problem with Komodo, and found a nice hack using Apple defaults:
defaults write com.activestate.Komodo AppleAntiAliasingThreshold 20
Is there a similar workaround for PyCharm, or is some other solution planned? I'd love to make the switch--this is really the only thing holding me back!
