I am a details guy. I notice when something doesn’t seem to be consistent. Such has been the case with the famous Dock in OS X. When put on the right or left side (right click on Dock -> Position on Screen -> Left or Right), it used to have a different look than when left on the bottom of the screen. Well, no more in OS X 10.9 Mavericks.
Who says Apple wasn’t working on improving consistency in OS X?
