The real reason is what makes the Advantage so hugely superior to the TypeMatrix and the Truly Ergonomic: the thumb clusters and in-line cursor keys. The cursor keys are placed in a 4th row that does not exist on other keyboards. Let’s take a look at what kind of options we had and what issues we saw that eventually led us to making our own. The on-board programmability, which has always been a selling point is much also much improved. As far as we know, the oldest attempt of full-fledged ergonomic keyboard is the IBM British Patent. Maltron and kinesis are about the exact same size. The new Advantage 2 even has textured and molded home row keys that make it immediately obvious that your finger tips are dead center on their respective home row keys. The Kinesis keyboard has the full range of function keys, but they are not much easier to reach than on any other keyboard. I disagree. Prolonged ulnar deviation can cause chronic wrist pain. The function of the both thumbs is limited to pressing the space bar! The thumb clusters are such an obvious improvement once you get used to them, that is seems impossible that there are keyboards without this feature. G and the H key) are very awkward to press. If price doesn't matter, i think Maltron is functionally better than Kinesis. This is obviously a major productivity/convenience issue, but not limited to that: It’s a health issue as well. In all other keyboard designs, some frequently used keys such as the Backspace, Delete, Enter or the cursor keys require you to move your hand, usually the right hand, away from its home row, feel for the key, press it and then awkwardly feel your way back onto the home row. Not having done this for well over a decade of continuous Maltron and Kinesis keyboard use, this absolutely drove me nuts on the Surface keyboards and I went back to the Advantage. Where applicable, VAT at the prevailing rate will be added automatically at the checkout. This is not the finger’s fault. This shift, in turn, offsets the hand to the left and to the right, and during a rapid typing, results in a constant mistyping or a slower typing speed. When your wrists are bent sideways or strongly upwards or downwards that gap narrows and.. ouch! The latest model makes a bunch of detailed improvements, but the basic design has been identical since the early 1990s. So, the lateral movement is executed with only one joint, with more effort and pain than the vertical one, and to a fairly small range of motion (about 20 degrees), This is why the lateral movement of the four fingers feels limited, awkward, and inaccurate, while vertically you can move them so deftly, delicately, and freely, with more than 180-degree range of motion. It feels better for a while, but this in turn stretches the muscles in the upper arm and the shoulder. The bigger problem is that, when certain muscle is strained for a long time, human body instinctively tries to relax it by changing the position of other parts. A great keyboard, which the Advantage 2 certainly is, goes one step further: not only can you type without injuring yourself, but it also helps you forget about the keyboard, concentrate on what you are writing and makes it feel natural and fun. The Truly Ergonomic is a mechanical keyboard but completely flat with neither tenting, nor enough of a split for my tall frame. Another group of ergo keyboards available in the market are more or less traditional, with certain features such as ortholinear key matrix, splitting the keyboard in half, and so on. They would almost never question the nearly 150-year-old QWERTY layout and restlessly add more keys around them, ever worsening the reachability problem. Eventually I couldn’t work full days any longer and even just typing a few words or using a mouse would cause pain and discomfort. My major gripe is the build quality which is more “bespoke custom job” than what you’d expect from a consumer product. A good 20 years later, I’m much healthier and have suffered no RSI related symptoms for at least 15 of those years. On the contrary, we love most products we cover here. What these design choices amount to is what makes typing on the Kinesis Advantage such a great experience: you never have to move your hands away from the home row. The Kinesis Advantage is part of only a handful of keyboards that don’t use the staggered key rows that originate in the requirements of the mechanical typewriter, but instead uses a columnar (also known as a matrix) layout.
