Can't we have a topic especially for people who don't own a Topre keyboard, yet want to post "expert" reviews of it,
Because if you can't have one, no one may enjoy one, right?
Given that the capacitative Model F is superior to the Model M, I see no problem in accepting that the Topre, due both to being capacitative, and having those springs under its domes, can be as good as people say it is.
The main accusation being levelled at the Topre in this thread seems to be that putting a spring under each dome, and using capacitative electronics, ought not to increase its marginal cost of manufacture all that much over that of a regular rubber dome... so it ought to be possible to buy a Realforce for less than a Unicomp.
Such a question doesn't have to come from sour grapes.
But there is still a valid answer.
Basically, the Topre design had a development cost. And the marginal cost of manufacture of a Topre keyboard is at least
somewhat greater than that of an ordinary rubber dome.
Only if enough people appreciate the extra quality of a Topre to be willing to pay
something extra for it - not its current price, but some premium - there's no point for them to try, by cutting prices, to expand from their current niche market, airport ticket counters and newspapers and so on, to make up for a reduction in unit margins by a significantly increased volume.
I guess a test might be this: when the Topre patents expire, do you seriously expect Logitech to run out and produce an imitation because they would think the improved feel would sell zillions? If so, it would make sense for Topre to cut prices and grow. If not, well, then it makes sense for them to stay where they are.
For that matter, haven't the Model M patents run out by now? Or at least the Model F patents, or the beam spring ones for the 3278 keyboard? Anyone out there making life tough for Unicomp? (Well, there
was the infamous Mechanical Touch keyboard... but as the result achieved was apparently not a success, difficulties in execution may have been what kept that sort of competition at bay...)
