Hopefully, this technology will make a comeback in general

This is great. If laptops gets thicker, people will have more space to take a good keyboard with them.

"Darfon says it is also able to tweak the resistance electronically, so the keys will have various degrees of pressure depending on the preferences of their customers."
Here's the patent: http://www.google.com/patents/US20130249658
If the pressure is adjustable wouldn't that imply an electromagnetic assembly? Wonder what kind of power usage that entails.
-
Probably less than you would think. From the looks of the patent, the switch is held in its neutral position by a permanent magnet.
There is another magnet in the frame of the switch which I assume when you press the keytop would induce an electric field in a PCB/coil below.
Some smart electronics could drive power back to increase/reduce the force you feel while pressing.
So there is no power being used when you aren't actually pressing on a key.

with fast enough electronics, this could make a very versatile tactile switch! first in a laptop :D
-
if it's expensive, I'll try and find a dead one a year after it comes out.

you can try to get the replacement keyboard part through the normal channels.

But that's a simple, easy thing to do.
Why would I want that?
