TL;DR I discuss my impressions of the newest version of the classic Kinesis
Advantage contoured mechnical keyboard, the Advantage2.
Mechanical keyboards
Mechanical keyboards have become a big business the last 5 years or so, with
clackity-clack Cherry MX key switches becoming all the rage amongst programmers
and gamers alike. In the age of ever-thinner laptop keyboards (and Apple even
getting rid of physical buttons and keys in recent Macbook Pros), the strong
tactile feedback and satisfying feel of mechanical key switches are a welcome
change for professionals who spend long days at the computer.
I was introduced to these keyboards through the Kinesis Advantage back in
2008. I was suffering from repetitive strain injury (RSI) pain at the time and
the Kinesis layout (with modifier keys at your thumbs) and lower key actuation
force was exactly what I needed. They are expensive keyboards (at US $\$$300 to
$\$$400, depending on the model and where you buy it), but given that they can
last a decade or more, properly taken care of, you can think of it as an
investment in your professional productivity and health.
I'm not an expert on keyboard history, but the two companies which popularized
keyboard layouts with thumb-based modifier keys were Maltron and
Kinesis. Since then, there have been other new keyboard designs taking
inspiration from these, like the open source Ergodox and Dactyl
keyboards.
The Kinesis Corporation itself has always been sleeper hit amongst programmers
with RSI issues. So I was interested when they released a new version of the
Advantage keyboard with some hardware changes and internal software
changes. They were kind enough to provide me with a demo unit to try out the
new features.
Advantage2: what's new
The big changes in the Advantage2 are:
The function keys are now proper mechanical Cherry ML switches rather than
the spongier capacitative ones in the older models. They're a big step up
from the old function keys.
New internal hardware / firmware bringing improved programmability for
modifying keyboard layouts and macros. Macros have been improved in some good
ways, too.
An internal USB-based "V-Drive" enabling you to edit configuration files
(layouts and macros) and install firmware updates on the keyboard
programmability and firmware updates from your computer.
Otherwise, not much has changed about the physical design of the keyboard
(which is already tried and true). It's missing a USB port for a mouse (which
I'm told had caused issues for users on KVM switches), but you can still
connect a set of foot pedals, which behave like generic programmable keys.
Easier programmability
The new programmability system I've referred to is now collectively known as
the "SmartSet Programming Engine". I updated the keyboard firmware using
the V-Drive, so at this time I have (this status report printed out by a
special keyboard macro):
Pressing progm - F1 mounts a special USB drive which contains an active
folder containing configuration files for keyboard layouts and macros, and a
special firmware folder for firmware updates.
Inside active, there is a read-only file state.txt which has some of the
basic high level settings.
The macro speed can be a big deal in practice. The original Advantage had a
fixed macro playback speed that wasn't too speedy. The default speed setting of
3 corresponds to 150 words per minute (WPM) corresponds roughly to a fast
typing speed. The top speed of 9 is 20 times faster, a blistering 250
characters per second (around 3000 words per minute). For longer macros, this
makes the output appear almost instantaneously. You can set the macro speed
globally or on a per-macro basis (since some macros need to be entered more
slowly).
The qwerty.txt file contains modifications to the default QWERTY layout. Any
remappings that you make using traditional onboard programming (by pressing
progrm - remap) are stored in this file. For example, I have long remapped
Caps Lock to left bracket [ and backslash to ] (for Python
programming). These appear in my qwerty.txt file as:
Things get more interesting with macros. For example, I used the keyboard's
macro recording mode (progm - F11) to set Ctrl-Alt-Shift-F to type This is a
Macro Example. This then appears in qwerty.txt as:
Any macros created onboard are similarly reflected in the text file, so you can
make tweaks to more complicated macros from a text editor (so-called "direct
editing").
Summary
For Kinesis users who take advantage of customization and macros, the
Advantage2 is a very nice upgrade for its improved programmability and the
better feel of the function keys.
If you are a new or potential user, and you can afford the investment (of money
and time to learn the contoured keyboard shape), it should be worth your
consideration over the increasingly long list of mechanical keyboards now
available.
