Previews, What Are The For, Are They Necessary?

What do I need previews for? Is it only for viewing my Library of images when I'm away from the Master files? I'm not sure I would even need that. My Library and Master files are all on a Mac Pro, I don't think I would need to drag the Library over to my MacBook Pro.

If the use for Previews (which increases the size of my Library) is only for portability, then I guess I'd like to turn that feature off. To do that, do I simply uncheck the two options in Preview Preferences?

Are Previews used in any other way when I'm using Aperture? (assuming my case where the Library and Masters are all available) Do Previews help in the performance of viewing and making Adjustments?

I can see where generating them takes time.

If I turn them off, should I, or can I delete the previews that have already been generated?

You can also do previews on a project basis. That is some projects can maintain previews for the image in them while previews are off in the other projects.

In can get very fine grained (and very confusing).
