On monday I ordered my shiney new powerbook. Having spent 20mins in total playing with a mac I think I'm going to need some printed assistance to get me through the first couple of weeks until I get used to the change in the way things are done. I have 6 years of running Debian GNU/Linux on all my machines and was wondering if there are books available that bridge the gap between Linux and OS X rather than the windows - OS X stuff I keep seeing everwhere. I picked up a copy of "Missing Manuals OS X" published by O'Reilly which is ok but I don't think it really covers what I'm after. Any suggestions of books are welcome but ones with a Linux/Unix slant would be of more help to me.
