Well I've been programming Bourne and Korn shells for about 15
years now. But I still pick python for anything that needs a GUI
or has to run as a daemon or does heavy network calls. I'd also 
use Python if I had to write a Web Browser or Word Processor or
Programming/Test environment.

In fact anything that needs more than a few hundred lines of
code. Shell is great for what its good at but orders of magnitude
slower and more resource hungry than Python for complex tasks.
Just think about how many processes get launched, the inefficient
text parsing, the nested shells etc. And as for data structure
support!

For sys admin type tasks, Shell is great, for applications its a
forced fit.
