Scott,
Seriously though, dovetailing by machine is going to be faster then by hand on multiple pieces with everything else being equal. You do have to account for setup time of the power tool method to determine which way you think will be faster or more productive.
Back to the sanding bit. I have to respectfully disagree with what you said about hand sanding, from my own experiences and learning in both the autobody field and woodworking/carpentry field. As an example, I remember taking a wood finishing workshop with Michael Dresdner around 14 years ago, if that makes any difference. He taught us to finish up with hand sanding using garnet sandpaper in the direction of the grain.
Also, from doing bodywork, I learned that finishing the sanding schedule by hand and by machine were different. By hand it was recommended to progress to the next finer grit.

In the end, whatever works best, and fits the agenda, of each individual is really all that matters. But in my world of projects, product, tool, customers and employees, I have to benchmark and make those calls. As recently as two years ago, I wouldnt have imagined a program where just about every single sanding task could be powered, with remarkable dust containment.
Sanding for finish is a repetitive task. Again, not unlike many carpentry tasks. If I have to cut 3 mortises in a door, is it better to set up a router or to use a chisel, and which will give me the more perfect result time after time and more efficiently?
So much has changed in recent years on the finish side...I like the timeless nostalgia of hand based craftsmanship. I will always value good brushwork a notch higher than good spray work. But that is in application. All steps leading up to that crescendo dont deserve that same honoring.
The only reason I can see anymore to finish by hand is if there is any kind of subtle scratch pattern happening in the power sanding steps. With granat, and good understanding of wood species, product, sander, grit, extraction rate and technique to avoid burn through, it is possible to see no swirlies or scratch pattern when stepping through 10 grits.
I was just working with the RS2 yesterday in fact and thinking about this whole discussion. In my own life, if I end up hand sanding, something has gone wrong.
