I will probably get hammered for this, but it really annoys me that the "finder" does not expose everything on the machine to my prying eyes. I don't need an operating system that obscures anything from me. I want to poke into every single little nook and cranny of the file system, device drivers, logs, config files, run levels, permissions.... I'm not interested in a "friendly" interface that pats me on my hand and shows me just what I need to know. I want to dig into the whole banana and find out everything I can.
So I spent an hour looking for something like window's "Folder Options" or 08r2's "god mode" console - where I could enable file extensions and hidden and system folders. Finally My good friend and colleague Wil Genovese told me to download "Deeper" - an apple utility whose sole purpose seems to be to enable various things that are "off" by default on a Mac. I can now see the whole file system (thanks Wil!). On to the next challenge!
