zope book

[j-marvin]

hi-

i am shopping at amazon and see the zope bible book.  it has an april 2002 
date.  i noticed the current stable release is about 2.7.  will this book 
be ok for awhile using 2.X.  i know when it switches to 3.X i will have to 
buy a more up to date book because it is suppose to be a big revision.
the web hosts will be a little slow to adapt too right?
i am only looking to get a year or so out of this book.  does it have
that much life in it if i buy it now?  looking at the amazon sales rank it 
seems popular and i thought someone might know.

thanks and happy 4th,
jim
