what is the deal with thimbles?

I see all these posts about thimbles and searching for the holy grail,
eer, thimble. what is the deal? I have several thimbles I love, most of
them gotten at estate/yard sales for a few bucks, usually in a lot of
sewing stuff. according to the day, the heat, the size of my finger I
use one or another. I don't get it.. what is it you don't like about
regular thimbles?
