I was studying at IKEA - yes, IKEA of all places, long story - and I noticed a peculiar thing about my HHKB.
IKEA was very crowded today, and really loud. I normally love typing up my review notes on my HHKB, but today I just wasn't enjoying it as much. Noticed I couldn't hear the thock at all, and it made me perceive the that the Topre switches were less tactile than they actually were. It felt like my fingers were numb, even though I was feeling the bump of the rubber domes.
Needless to say, I think the most prominent part about the Topre switch is the sound it makes. Without that sound, the tactility of the switches are just mediocre.
