Re. that Python discussion.. I don't see any runtime performance issues with those apps I run. There seems to be a longer-than-normal startup time (compared to other applications). I suspect this is not entirely due to it being a scripting language (after all, command line scripts have no delay to talk of), so I suspect it's something to do with Python's UI elements. Which means that it could well be possible to fix that particular problem.

Re. left vs. right side of brain: The whole issue isn't particularly scientific, it's much more complicated (and balanced) than that. Left vs. right side brain usage is a discussion that mostly takes place in popular media. It doesn't mean it's true.

Edit: Here's even a link about it: http://en.wikipedia.org/wiki/Lateral...brain_function
