I've been running amd64 on my desktop since 5.3 without any real 
problems. But I only picked hardware that had drivers available.

Some things to keep in mind:
1) no binary nvidia graphics driver 
2) no flash plugin
3) java is cumbersome.
4) no win32 codecs for mplayer

ad 1) I've got a Radeon 9250 that's supported by the native Xorg & DRI
driver, so no problem. I don't like binary-only drivers anyway.

ad 2) So no annoying flash ads either. :-) I can live with that.

ad 3) I don't use it anyway.

ad 4) Works fine without them, AFAICT.

Stuff like emacs, firefox, gimp, sane, imagemagick, audacious and
mplayer all work fine. I haven't tried openoffice, bacause it's huge
with lots of dependencies and I prefer LaTeX anyway.
