The differences aren't so fundamental or important: it's not an entirely new language, just some ugly old things are being removed or changed in incompatible ways (at *some* time it was supposed to happen - but could not happen on the 2.x series which has to remain backwards compatible)
Also, Python 3.0 will be released simultaneously with 2.6, and there will be other 2.x releases. Python 2 won't magically disappear from Earth, I don't think Linux distros will come with Python 3.0 by default anytime soon (perhaps not before 3.1).
So learning Python with a book targeted to 2.5 isn't a waste of time - not at all.
(This subject has already been discussed several times in this group.)
