Does anyone have experience with PyS60 mobile development
I've written a calculator, that I'd like to have, and made a simple game. 
I wrote it right on the phone. I was writing in text editor then switched to Python and ran a script. It is not very comfortable, but it's ok. Moreover, I was writing all this when I hadn't PC nearby.
It was a great experience!
I am in the position of having to make a technology choice early in a project which is targetted at mobile phones.  I saw that there is a python derivative for S60 and wondered whether anyone could share experiences, good and bad, and suggest appropriate IDE's and emulators.
Please don't tell me that I should be developing on Windows Mobile, I have already decided not to do that so will mark those answers down.
