Kinesis Advantage Keyboard

Back when I was finishing my undergrad degree, my final year project (which is a big part of the final degree exams in Trinity) was in Java on a Sun SPARCstation 4 (at the time, one of the more powerful boxen you could get access to as an undergrad). The project was a fair bit of fun, writing a robot controller in Java just as 1.2 was coming out of beta. Lots of long hours were spent in that lab with three or four others working on their projects, and quite a few all-nighters interspersed with the odd game of networked bomberman :D I even managed to get a published paper out of it.

Bomberman!

The downside to all of this fun was the Type 5 keyboard.

As planks went, it wasn’t really a bad keyboard – no Model M, to be sure, but better than a lot of the cloned generic planks that were out there at the time. And the mouse wasn’t as bad as fingernails on a blackboard. I suppose. The thing was, six months of long hours on that puppy, combined with a few hours a week of aikido did a right number on my wrists. As you’d probably expect I guess – this kind of thing does tend to stress the joints if you get it wrong:

Anyway, when I started my PhD I had only one non-negotiatable demand – I wanted a good ergonomic keyboard because sharp stabbing pains in the backs of my hands and the insides of my wrists didn’t seem like a fun way to spend a day. I did a bit of searching on the net, and found the Kinesis Contoured keyboard. Lots of testimonials, clever design and nifty looks. I ordered one, had it shipped, and happily unwrapped it and started to use it.  And it was magnificent. It took about a week to get back to my normal speed of typing after the switch (I got taught to touch-type by nuns on old manual typewriters in secondary school, which I suppose says rather a lot about the school and what they expected of their pupils – it also explains why I managed to break two computer keyboards before I learned that you don’t need to actually use a lot of force on them :D ). Once I was back up to full speed though, I found that that speed then increased. Not by a massive amount, but 10% is 10%. I also found that I had no pain in my arms at all, even after several hours of typing.

So, a success all round and I proceeded to use that keyboard for about five years until I literally typed it into oblivion – one of the circuit boards in the keyboard failed, and rather than ship it back to California and pay for the repairs, I just used my laptop instead. Eventually, however, I got tired of that and went and bought a new model (Kinesis had just brought out a USB model the year earlier). And again, I proceeded to type the daylights out of that one as well (it’s still holding up today actually, these things are really surprisingly sturdy).  I can’t recommend them enough to those who have RSI from typing.

However.

They have two major problems – firstly, they’re rather expensive at $300 apiece. It could be worse – at one point you could only order them from California, so you had to have them shipped to wherever you were (that’s now changed, thankfully, there are a lot of shops stocking them in Europe these days). But $300 is a decent netbook these days, so it’s quite hefty still.

The other major problem is that the bowls the keys sit in. They’re central to the design – they let you just curl and uncurl your fingers naturally to reach all of the keys – but they also collect dust, dirt, grime, fluff and eyebrow hair like magnets. And so, after a short while, you end up with something like this:

Which looks bad enough from this distance, but get up close and look between the keys and it’s downright unpleasant. So today, I got to spend a long half-hour pulling all the keys, cleaning up the bowls, cleaning off the keys and replacing everything.

Ew. But at least it’s clean now. Mind you, it’s nothing as pretty as Josh Carter’s painted version:

  1. Frequent hand-washing has been known to retard the formation of hand cheese by as much as 90%. Just saying.

  2. I have a similar “sun breaking through the clouds” moment when I got my Kinesis — I was finishing up my BS in CS and my hands/arms hurt so bad I shelled out the $300 … and drove 100 miles (holding the steering wheel palms-only) to get the keyboard same day. It’s been an epic love story ever since.

    Also, when I got my second one (to have one at home as well) I got it in black. REALLY holds up better.

  3. Who knows – maybe the material researchers in the future will supply material that is hating dust – so if dust wants to settle down, it cant, eventually leaving all the dust wiped away.
    And not annoying the keyboard.

    Is the speed inrease really that good by the way? I find myself typing quite fast already with all default keyboards (pc104, pc105 etc..), so I am a bit afraid to switch…

    I was thinking of buying one of those keyboards with the small LEDs on each key, but even if I can afford it, they appear to simply cost too much :(

    • The speed increase is about 10% alright mark (at least it was for me) and you don’t lose your speed on the planks (as you find when you have to use laptops). As to the Optimus keyboards, they look magnificent, but I’d hate to have to clean the gunk out of one!

  4. I have had my Kinesis classic keyboards repaired two times each since 1997; that’s how much I covet these keyboards. I would only like to request laptop-like quiet, soft key action.

    Okay, near perfect input tools: kinesis keyboard with foot pedals for mouse actions and the forehead tracking mouse pointer.

    • I got the foot pedal with my second kinesis Bob, but to tell the truth, I don’t tend to use it very much at all.

  5. This looks awefully lot like the Maltron.

    • The two are remarkably similar, though there are minor differences. The Maltron was far more expensive when I went looking initially though, and to be honest, I’ve never had any problems with the Kinesis so I just stopped looking. There’s a Maltron-v-Kinesis (albiet by a Maltron user) here: http://www.tifaq.org/archive/kinesis-vs-maltron.txt

  6. pretty cool stuff..

  7. I’ve been using Kinesis keyboards for about 10 years now. One at work and two at home. My fingers and wrists would be goners without them. My kids love them; my wife insists on having a standard one around.

    The palm pads get a bit funky too.

  9. What I want to know is, how you did this:

    pulling all the keys, cleaning up the bowls, cleaning off the keys and replacing everything.

    • Simple enough – Kinesis supply a tool for pulling keycaps off their mechanism (and you can buy them for a euro or two off a dozen places on the net), you pull all the keys, keeping track of what goes where (do one chunk at a time helps), then lots of compressed air and a dry paintbrush to clean out the gunk, and then put the keycaps back on. Takes less time to do it than to describe it, almost…
