So has much as I am on record for not really liking the whole ribbon interface it looks as if I've zero choice about using it...
Prototyping a New User Interface for OOo - July Status Update for Project Renaissance - GullFOSS
Where M$ lead OO.o will surely follow :(
To me, it doesn't make sense to have the category selection underneath the main buttons, because it seems your eyes have to do more work. The direct top-to-bottom approach of the MS Office ribbon interface seems more natural.
FFS If they put this on I'm gonna have to migrate to abiword
this way is far more intuative than the original versions of MS and OOo
