I'm going to second the thoughts about Nvidia, flash and virtualbox -installing anything on Qemu is downright masochistic, even with kqemu.
1)Automounting mechanism, so that when I plug an SD card in it shows up in GNOME the way that it does under Solaris & Linux
2)more reliabled gnome/ports integration -this has improved light-years since I originally used gnome on 4.1-4.6, but there's still weirdness with the way things show up; it's not as predictable as Ubuntu.
3)Better photo/camera tools -this one may completely be me being a spaz, but even after installing gphoto2 I can't find a way to hook up my camera and have it recognized in Gnome. It seems like gphoto2 is a library under FreeBSD but a program under Fedora and Ubuntu.
I also have some trepidation about using wifi with FreeBSD, but until I get my laptop fixed it's a moot point.
