I think it does increase saturation because it gets rid of any reflections that could dull up the color. No window reflections = a plus, and it lowers the required shutter speed/f-stops which is cool. Only downside I can find is that on my camera (which isn't exactly a D1 or anything) it increases the visibile noise significantly. No biggie.
Spent some time playing with it the other day... nice.

I've never used a polarizer. I've heard though that you need to turn it until you get the shot you want. Is this correct? One reason I've not used one is I feel that I wouldn't be able judge the best shot looking through the view finder. I guess that may just be a little self doubt from a newbie.

That depends. If you have a lens with a fixed front element you can fit a linear polarizer on it. A fixed front element is one that doesnt rotate during the focussing, a lot of Canon L lenses are designed that way

Polarizers are fantastic especially in landscape photography. I use it a lot there. It darkens the sky in certain angles. However I almost never use it while photographing airplanes except in rare cases when I like to avoid reflections in windows. I think polarizers make metal on planes look a bit dull.

Wietse, AF systems in cameras have problems focusing through a linear polarizer, that's why it's usually circular filters that are used with these. Difference between a linear and a circular is that the circular filter (which in fact also has a linear element) has a second element between the linear filter and the lens. This element "unpolarizes" the light in a circular way to make it possible for the AF to work.
This is why it's so difficult to AF through polarized windows such as the ones in cockpits, they are linear.
