for the first 2 years of my mac life, i left it hidden and on the bottom
now i've wisened up... and put it permanently shown on the right with a moderate size (about 1.25 cm icon height) and magnification turned off
Why is it wiser to have it on the right?
I guess because you have more screen real estate horizontally than vertically.
That's why I have my Dock on the right. Hidden, too.
I'm only using it for my stack of document templates.
But if it is hidden on the bottom it takes up the same room if hidden on the right. The only thing that can change is appearance (no reflection).
I think you're missing the point. Yes it takes up the same amount of room on the right vs the bottom, but there is more screen real estate on the right (screens aren't squares, especially wide screens). Also, most word documents, webpages are setup in portrait layout, not landscape, further making the real estate on the edges available.
