I had not been able lately to find a good, reasonably stable kdelibs-based-software (amarok, digikam, k3b?, the whole of kde if it's not asking too much) port to Windows and OSX. Even Calligra only has ATM AFAICT a "considered very unstable" MSI installer and no OSX installer/port that I can find.
So, even if it has the potential to be "a cleaner approach to a cross-platform office suite", it's not living to that potential.
OTOH, LibreOffice3.6 is working AOK -- and consistently -- on the three platforms I use today (Kubuntu precise, W7, Mountain Lion).
