I think that we need to keep in mind that Incra Tool's did not come into existence to make woodworkers happy, but their purpose for being in business is to make money.
With that goal in mind they created tools that woodworkers would buy. The tools had to be such that they would be so well liked that a lot of people would buy them. They have accomplished that goal and apparently are doing very well.
Certainly micro adjust is not a neccessay feature on a router table's fence, but for some folks such as myself, I wouldn't want to be without it. This is probably due to the fact that I have gotten used to it. Had I never used the feature, I probably would never missed it.
I'd like to hear from a member that has a an Incra router fence with micro adjust that is sorry that they bought it.
Yes, the feature may well fit into the list of unneccessay luxury items, but what is wrong with that. I'd love to have a high end TS, but it would just be a luxury as my present saw does all that I ask of it and it does it with ease.
Sure would be a boring world if we were all alkike with like needs, wants, and ideas wouldn't it?
