"First to market with pressure-sensitive keys on a keyboard"
uh? no,
Microsoft: 2009 (didn't work it seems )
Topre: 2015 (didn't work it seems )
The Wooting: 2016 Kickstarter 130k $ pledged over 30k $ goal, TKL, full mech, MX compatible, switch swapable and analog over all keys (1st pledge was not too expensive for the type marketed, retail model is quite higher priced, 100$ vs 159/199$/€) downside DXinput compatible game for analog and probably price (tho on par with the Ryos MK FX )
Roccat: 2017
tho i love Roccat ... their Ryos TKL Pro was a real good keyboard, sturdy feeling, excellent shape and wrist rest, the original Isku's were an oddball for me .... clearly inferior to the Ryos line the price wasn't that inferior ... it was rather between standard "gaming" membranes (60-80$) and Ryos Mech (100-150$) at 90-129$, depending the retailer ... and not really an edge to justify it, that price bracket is now taken by the Isku+ at 131chf and the "edge" is the 6 pressure sensitive key this time.
