A question:  are variable capacitors actually in use? 
They seem not nearly so common as variable resistors.

I have seen only two common applications in my very limited experience.
1.  Radio reciever tuning units.
2.  Foot volume controls in older Hammond Spinet organs.

I am sure there are others.
