You nailed it. I polish maybe twice a year, Spring & Late fall. Wax quarterly. Polishing and than waxing by hand can be pretty time consuming. With the machine you can do it in about 80% less time. I haven't waxed by hand for so long, I can't remember how long it takes by hand. Appying wax to my car by machine takes under 10 minutes.
The machine is more effective removing swirl marks or other damage. The darker your paint, the more damage you will incur over time (well, you'll notice it more, all cars get swirl marks, etc). Using polish by hand, you just can't work out issues the occur to the paint.

I always thought polish is like cleaner/shiner, and wax is well… just a protective shield, so I would only use polish and wax like maybe every 4-5 polishes. Also is there a huge difference between machined polished/waxed and hand polished/waxed quality. I don’t mine taking time to do things manually by hand, but if there’s a quality difference, I am thinking of getting the porter cable. I want my car to shine enough to blind a person during daylight.
