Despite the math, I prefer the edge I get with the Tormek, and I end up needing to sharpen less often, not more. I don't try to get as fine of edge on a gouge as I do on my bench chisels or plane irons, but it's still sharper than I get off the dry grinder. And yes, I can slap a gouge in the Tormek, get a sharp (reasonably sharp) edge within 20-30 secs, and get back to turning. I don't dispute, however, that a lot of very good turners produce great work sharpening with coarser methods. If possible, try both, then decide what's best for you.
