I'm not sure how helpful it would actually be to have analog sensing in a keyboard. For gaming, sure it would be fine, but as far as I've seen, games have 5 settings: walk crouch, run crouch, walk, run, and sprint. Look at Skyrim: Default config is LShift for walk, LAlt for running, and LCtrl for crouch. All that you need is right there. There are enough keys on the keyboard to let you have those commands without having analog controls. As for typing, maybe the harder your press down determines how it repeats, but for a majority of the people on here, that's completely unnecessary. I think that it's pointless for PC gamers and typing, but that's my opinion. As others have shown, other have different opinions.
As for this guy, love his videos, but hate this one because he ripped apart a mechanical keyboard. FOR SHAME
I know I would pay for the extra feature. Just so any console peasant couldn't use it as leverage against me.
If they are using that against you, you know that they are grasping at straws, so you need to counter with "got anything meaningful?"
