I am just getting used (more or less) to QT3 and QT4 is released...

Why is QT4 better ? Ease of use, features, ???

The book programming with QT4 is unavailable on Amazon.
Is there another site where I can buy it ?

Qt4 is a bit more complex, so it's easier to learn Qt3, but Qt4 has a lot of new features. Like PDF & SVG support, more powerful painting engine, unit testing library, much cleaner .ui file handling, MVC paradigm, ...

Probably such book doesn't exist yet, but you might try this (http://www.qtcentre.org/index.php?option=com_weblinks&task=view&catid=14&id=27).

I'm assuming you want to use Qt in the very long term.
Without looking at any features: Why should you not upgrade to Qt 4? If it's only that you don't know the API, I can't believe that a switch to Qt 5 would be easier... ;)
