Two kinds of people are likely to want the Kinesis Advantage Keyboard: efficiency freaks and repetitive stress injury (RSI) sufferers. The Advantage is an unusual beast that promises a better keyboarding experience than conventional, flat keyboards. Does it? I firmly answer maybe, although enough people swear by them to make me think that, if nothing else, those with wrist pain or repetitive stress injuries benefit from the placebo effect if nothing else. There are two major barriers to using the keyboard: the first is retraining, which can be overcome relatively quickly. The second is the $300 retail price.

Still, once one adapts, typing becomes fun, like learning a secret. The Advantage’s curves remind one of advanced spaceship controls from a science fiction movie, as this manufacturer-provided picture demonstrates:

Sit-Stand Workstations
We have tested computer use when sitting and standing in different ways (see EHAW). The problem with standing is that when you raise desk height for keyboard/mouse use you need to also raise screen height above the desk or you get neck flexion. Also, for standing computer work the computer fixes the person’s posture there is greater wrist extension and pretty soon people end up leaning which also compromises their wrist posture, thereby increasing the risks of a musculoskeletal disorder like carpal tunnel syndrome.
 
In our field studies of sit-stand workstations we have found little evidence of widespread benefits and users only stand for very short-periods (15 minutes or less total per day). Other studies have found that the use of sit-stand stations rapidly declines so that after 1 month a majority of people are sitting all the time.
 
Others have proposed a treadmill workstation or a bicycle workstation. Both of these have been tested and shown to decrease computer work performance (typing and mousing slows down and significantly more mistakes are made).
 
Sit-stand workstations are expensive and generally ineffective in addressing the issues to hand.
 
The bottom line:
Sit to do computer work. Sit using a height-adjustable, downward titling keyboard tray for the best work posture, then every 20 minutes stand for 2 minutes AND MOVE. The absolute time isn’t critical but about every 20-30 minutes take a posture break and move for a couple of minutes.  Simply standing is insufficient. Movement is important to get blood circulation through the muscles. Research shows that you don’t need to do vigorous exercise (e.g. jumping jacks) to get the benefits, just walking around is sufficient. So build in a pattern of creating greater movement variety in the workplace (e.g. walk to a printer, water fountain, stand for a meeting, take the stairs, walk around the floor, park a bit further away from the building each day).
 
So the key is to build movement variety into the normal workday.

As a professional journalist and software development hobbyist, I generally spend between eight and eighteen hours a day using a computer. This effectively keeps me chained to my desk most of the day, and sometimes late into the night. To combat the physical discomfort of prolonged computer use, I reinvented my home office environment with a focus on ergonomics.

The first thing I did was purchase a better chair—that's easily the most significant thing that you can do to make your office life better. After that, I started to look at desks. Last year, I became intrigued by the idea of a standing desk—a surface that is high enough to accommodate working from a standing position. Further research into the subject convinced me to buy a height-adjustable desk that can elevate to a standing position. After using it for most of the year, I doubt I'll ever want to go back to sitting all day.

The majority of keyboards are based on the staggered key arrangement of typewriters from the 1860s:

The Truly Ergonomic Keyboard design follows the symmetric shape
and neutral position of the human body promoting a healthier posture:

100% of the keys in 60% of the space

The Truly Ergonomic Keyboard (green outlines) has a smaller footprint,
allowing you to keep the mouse close to the body's neutral position.
This reduces stretching and helps to minimize wrist and shoulder strains.

As anyone who's worked in an office would know, Herman Miller's Aeron is the chair to have at your desk for both comfort and status. As a guy who's worked at his share of Silicon Valley startups the net boom and bust, I've only had the privilege of stealing Aerons from coworkers when they weren't looking; never actually being actually senior enough to sit on one full time. Things are different now, my fellow prisoners, with Herman Miller's latest creation, the Embody. Its $1600 body was designed by Bill Stumpf, who was also responsible for—among other projects—its famous predecessor, the Aeron. It's no surprise that the Embody feels very good.

Perhaps today's touchpads are intended to be more fixtures than usable input devices, a signal to the user that he should purchase a quality Bluetooth mouse and stick that in his laptop bag. But why? Over the past 20 months, Apple has shown me quite clearly that touchpads can not only be usable; they can be almost more fun and comfortable to use than a full-blown mouse. PC laptop makers don't seem to realize that aluminum panels and glossy display bezels aren't what make MacBooks great. It's the ergonomics, stupid.
