Detractors of Topre-switch keyboards tend to use descriptions such as, "it seems like nothing more than a high-end rubber dome to me." I have often wondered what is meant by "high-end rubber dome". Are there any examples of such a keyboard other than those that employ Topre switches?
Having compared many different types of keyboard switches in addition to Topre, including Alps of various kinds, Cherry mx of various kinds, membrane buckling springs, capacitive buckling springs, beam springs, Hi-Tek space invaders (tactile and clicky), Matias tactile clicky, Honeywell Hall effect, various linear switches in terminal keyboards, and rubber dome keyboards packaged with modern PCs, I find that the aural and tactile feedback of Topre switches is distinctive. To me, the tactile feedback from a Topre switch might be likened to that of a weighted piano key on a "real" piano (as opposed to an electronic piano keyboard).
I happen to like Topre switches, especially the heavier variety in my RF 87ub 55g, but I would not expect everyone to like them. Moreover, Topre is not the only switch that I like.
Periodically, I do a reality check by rotating through various keyboards in my collection to see if my preferences have changed. I really want to like Cherry mx switches, because I wish to take advantage of the abundant styles, colors, and textures of keycaps for them. Unfortunately, each time I try or re-try a Cherry mx board I am disappointed, and returning to a Topre-switch board is refreshing. In fairness, returning to a buckling spring keyboard (especially a capacitive buckling spring, such as the IBM XT) is also refreshing. Despite the differences between my IBM XT and RF 87ug 55g, I like each of these equally well, and either one is greatly preferable to any Cherry mx board I have tried.
We keyboard enthusiasts are fortunate to live in the midst of many excellent choices among keyboards and switch types. There is also no accounting for taste, and advocates of one particular switch or another will likely continue to remain baffled by the contrasting preferences of others.
