The two Python IDEs I've been watching, DrPython and SPE, both got Christmas upgrades. The new DrPython release looks like mostly bugfixes, but the SPE release adds a neat new class diagramming feature.
My earlier characterisation still holds: I like the speed and stability, but dislike the unPythonic coding style and awful GUI layout of DrPython. I like the shiny features, but dislike the instability of SPE. And I'm still using SPE until PyChecker or another feature craps out, at which time I fall back to good old Emacs.
And I'm still fighting the urge to create yet another Python IDE.
