Advantages of Machined Brake Tracks?
What are the advantages and disadvantages of machined brake tracks? I'm just a humble commuter, not a racer or anything, and I'm wondering if its worth the extra money. I've search google but to no avail.

+ Prevents brakes on a new bike from squealing.
- Unnecessarily takes metal off of the sides of the rim where the brakes will be wearing off metal anyway.
Bottom line: Marketing

The machined rims do hold up to tolerance better than non-machined ones. I true my wheels to +/- 0.001" when new. The machined rim has more exposed surface area for braking vs. a smooth surface. Manufacturers usually add a little more material to compensate for final machining.

Machined rims are smoother than pinned rims. All pinned rims, i.e. not machined, I've ever used have a slight annoying bump at the joint. Even after miles and miles of use along with removal of lots of sidewall material (braking wears the surface), the bump is still there.
