i think you misunderstood what your statement was inferring. If you were talking about gingerbread specifically, then you may be right, but then again i'd like to see it proven before voicing an opinion. My issue is with your generalization that the n900 cannot run efficiently any OS released in Q4 of 2010. It all depends on the the basic hardware requirements of the OS, the date of release has nothing to do with it IMHO. For example the HTC HD2 is able to run android because it meets the basic hardware requirements. The release date of the OS or the handset had nothing to do with it,
