Yes, you most certainly have the option to switch to OpenOffice, BUT it is
only a matter of time before OpenOffice has a ribbon as well. The ribbonized
prototypes are already out there.
If you have Java 6 installed on your system, you can test-drive the ribbon
prototype yourself at

If you don't want to test it (or don't have Java), just take a look at the
example screenshot at

So what will you do once OpenOffice starts using ribbons only? Will you look
for yet another office suite?
Good or bad, I'm afraid that eventually you will have to learn to get used
to the ribbon as more and more applications are switching to a ribbon-style
interface. And then the question becomes, why not start learning to use the
ribbon now?
But what I really don't understand is: you were a 'happy' Office 2003 user.
Why change? Why upgrade to Office 2007? Or why move to OpenOffice. What has
suddenly changed in Office 2003 that you no longer like it?
