And an example of what women collect (in case you talk to one that don't get oil cans either

) Art Glass, figureens (spelling), and collectors dolls...When do you see any of that in use (dust collecting don't count)?...virtually never!
We collect TVs for the same reason some of us collect antique cars. Not to be some rusty scrap sitting in our living rooms and yards respectively, to be looked at (like those 'OTHER' things mentioned), but to be used periodically as a fun trip back in time, an example of technological history/progress, and as a means to do what they were made to do for us.
An odd thing is that as a child of the early 90's, and a collector of radios and TVs of the 30's-70's, I often to my amusement find my self perceiving things from the 80's-mid 90's to be more ancient than the things I collect...Despite the opposite clearly being the case.
