VGN-FW31ZJ 64-bit experience

[DeLorentz]

Dear all
Is there someone who owns this new model? I am contemplating the FW21Z or FW31ZJ and can find the only major differences being the OS 32-bit vs 64-bit and a ever so slightly faster CPU.
Apart from gaining the full memory benefit from 64-bit, is it worth the extra money? Please get in touch on ejrossouw@freeler.nl if you feel you can share your experience with me.
Many thanks
