It looks much worse than it is, I can't really feel the odd zig zagging pattern with my finger and the pits themselves feel pretty smooth to the touch. No nail-catching ridges or anything.
Is this a big deal? The car has about 62k miles and is just over 12 years old at this point.
The images are bigger and clearer on imgur.

it almost looks like casting defects for the pitting. for the waves it could be milling marks. I would take a verner caliper and measure your lobes at the peak lift, and also do a visual inspection on the lifter assembly. If they are all within around 5 thousandths of an inch i would not worry about it because it is a roller camshaft, you would only need to worry if it was a flat tappet.
