If you're just a desktop user, then I recommend sticking with 32-bits (and a PAE kernel if you have gt 4GB RAM). I agree. One of the biggest problems with 64 bit desktop systems is Flash: the Adobe implementation is still in alpha (and feels like it), and the Gnash implementation is even further behind. Let's clarify the Adobe Flash situation: on _some_ hardware, users have no problems with 64 bit Flash. On others, it is a mess. I suppose that Adobe is slowly adding hardware support and that is why it is still an alpha.
