Realization this morning: as far as I understand, OpenACS works just fine on OS X. I can't think of any reason not to buy a Titanium PowerBook instead of something else. God, life is looking good :)
Any reason I shouldn't do this for my developmental computer? It seems like once Postgres and Aolserver are installed, there shouldn't be any difference, right? CVS should play well with Linux, shouldn't it? Anything I should be worried about?
Side benefit for OACS community: I can help maintain and test the OS X install docs. :)
