I would some what agree about the 25mm but a 17mm is not that far off being a normal I think the exact is something like 21mm or so I have read that 42mm on 35mm film is the mathematical normal. Either way I would say get the prime 99% of the time, I do think combined with looking at great photographers work a good length of time spent with a prime does help with your photography. Worth looking at where most photographs are taken but a lot of people end up using zooms at the two ends of the range.Of these, the 12-40 as it is what I want for my next lens
THAT said, I'd suggest a nice normal prime as a better option and while you have the 17/1.8 listed, I'm old school enough that I think there is little better than to take my camera and only my 25/1.7 out for a day. The discipline of shooting with a fast normal prime is something that will help all photographers get better.
So, I'd really say get the Olympus 25/1.8 instead. Read this for more info on why: Finally, Some m4/3 MTF Testing: 25mm Prime Lens Comparison
