How terrible are nail holes in the wall?

We have made about a million nail holes in the wall. They are all from small nails, except for the 4 really big screws that the previous owners put in the wall.

Ya know...up another inch, new hole...move it to the side 2 inches, another hole...stuff like that.

But, if I spakle, I'd have to repaint because we don't have the beige paint that the previous owners used...

Just thinking about if/when we sell.
