Sounds like a standard rubber dome with added marketing
BS... erm, spice.
Rubber domes
are tactile, if they didn't specifically mention it having springs or some other mechanism, assume it's just a rubber dome with 3-4mm key travel.
The Poker II is programmable, so ALL the keys can become macro keys
You have 2 extra layers on the board, the Fn layer and the Pn layer, so you can program a bunch of macros into the Pn layer and hey presto.
Also it takes up less space on your desk, so you have more space for a pen tablet or large mousepad.
