What do applications on OS X look like when maximised?

It seems that every single screenshot of applications on Mac OS X display applications un-maximised. I understand why (maximised apps make the space around the dock look wasted) but I’d like to see what it looks like, so if anyone on OS X could post a screenshot, that’d be highly appreciated.

Also, if you use OS X, do you actually run your applications un-maximised?

(And yes, I’m asking a lot today)
