one of the reasons i mentioned how even older missing manuals is still good (esp. for recent switcher) is that you can find those in public libraries. i found missing manuals to be a good read, but not a very good reference. so i didn't want to buy it because i'd read it once and be done with. but public libraries often have some copies, they are not the latest but plenty useful and they are free! i just thought it's a good way to get your foot in the door and get started using OS X.
i will probably go take a look at a panther one to see if there's something really useful to learn.
