For myself, the answer is yes. I'll wait an extra month or year to get a console if I can get it in the original box. Of course, I kind of take things to extremes -- I don't believe in putting loose manuals with game boxes they didn't come in originally, even if it's the same game I also stay away from boxed systems that are ugly or beaten up as much as I can - my worst-off system box would be that for my SNES Model 2, and it's still very presentable (just a bit of roughness around the edges).
Of course a boxed system is worth more than a loose one, but that's not the reason I search them out (seeing how I always have to PAY more). I like looking at the documentation and the box design, and of course I like shuffling about the wall of boxes on top of my desk. Adds to the decor ;D
