This is my current daily driver. A compact, 60% keyboard made with 
Topre-designed electro capacitive keyswitches. More inexperienced, misguided 
keyboard enthusiasts will tell you that Topre's proprietary switch mechanisms 
aren't worth paying for because they're "glorified rubber domes". What these 
people fail to recognize is that "rubber domes" aren't an inherently bad 
quality in a keyboard, assuming the mechanisms are built well enough. I've 
seen keyboard YouTubers boast about how they've "vastly improved" a friend's 
typing experience by building them a new keyboard using Cherry MX derivative 
linear switches, while tossing out their supposedly terrible Dell keyboards 
that happen to be made with Alps SKCMs and NMB domes with sliders that would 
have provided vastly superior typing experiences if they were just cleaned 
and refurbished, but I digress.

As much as I love the feeling of the sliders moving through this keyboard's 
plastic housing, I'm just not a fan of any of the layouts that can be enabled 
on this keyboard via the DIP switch block accessible from the back, under a 
removable cover. Thanks to someone over at the GeekHack forums who goes by 
"hasu," most Topre popular boards have been reverse-engineered, so I was able 
to set up a custom build of QMK relatively easily, after rewiring the 
keyswitch PCB to a new MCU (the ATMega32u4 on a Teensy 2.0), and write my own 
custom keyboard firmware.
