At some point - AFTER the major update - I'd love to hear more about this since it is something I've wondered about from the start. The single "advantage" I see in a regular keyboard is the totally separate keys. You either hit the right one or you don't. Very simple, at least in comparison to the TB.
I could see the narrow keycaps on the TB as perhaps being necessary because individual keys may really suffer from whatever mechanism (butterfly or whatever) you chose to use at such small sizes. But since the 6 character keycaps greatly increase the complication of hitting the wrong spot, I wondered why they couldn't all be 3 character keys.
True, the characters on the ends are on narrower parts of those keys and, if separate, that may create issues I don't have the knowledge to know about. But then, no reason I could see why those keys couldn't be made the same width. Certain is room towards the center by just making the metal connectors narrower. And you can always expand to the outside - you'd simply have a TB that is ever so slightly longer. Considering the competition, that seemed like a non-issue!
So, I'm trying to figure out why that would be an issue. Based on my experience with the TB, I certainly assume you are correct, but some day I'd like more insight into it.
I'd also like to know who came up with the original basic concept because while many things are clever about the TB, I'm most impressed that someone even got the basic idea in the first place! That "basic" stuff would be doing everything with just 36 places to put your finger (not counting the space bar) and doing everything else in layers. The details in implementation certainly are important too and in many areas, I'm impressed with the choices. But without that starting concept, we never get to the other details!
