OT - I'm seeing more OSX based screenshots of cross-platform tools. Is it just for aesthetic purposes or is there a trend where more and more devs are starting to use Macs?
I count at least 8 Macs, two more that may or may not be Macs. I don't see any blatantly non-Mac laptops.
To be fair, I can't be sure it's not a session on, say, PyObjC, but I also found this: http://www.flickr.com/photos/shimizukawa/6142969129/in/set-7...
Five Macs, possibly a sixth hiding behind one guy's head. Two non-Macs (one looks like a thinkpad and I think the one in the lower right is a vaio).
Last few times I've been to (Euro) Python conventions, I was actually surprised to see a lot of really skilled guys doing real computation (3d, molecular modelling etc) while happily running Windows on their laptops.
I flew back with a MBA and now ask myself, why didn't I do this much earlier.
