I fully agree, yet I change things around often and I think I wouldn't feel as guilty drilling holes into or mounting stuff onto unfinished plywood as I would on a nicely painted "wall"! I also feel that running into and banging into plain wood walls leaves less noticeable marks and scuffs. :)...
Jloehlein & wb4rt: Cool info!
Did you somehow support the adjoining and the free plywood edges?
I realize I may be over thinking this, but experience in Oklahoma makes me wary of leaving any large open areas behind these wall boards... any opening at all would allow crickets and therefore...
