i have encountered nothing that is not working, and ive encountered a lot.

here's a brief list of things that definitely work for me:
the point of this is to illustrate that everything works, except the things that dont. if you havent seen anything that doesnt, dont worry.
01) phone/contacts/conversations
02) openvpn
03) gps/maps/drive/turn-by-turn-directions
04) ssh over wifi/usb/wifi-hotspot as root or user
05) vncserver {vnc-ing INTO the n9, not FROM the n9. havent found a vncclient yet}
06) wifi-hotspot {joikuspot. you have to run a terminal cmd first}
07) firefox {fennec v11~a1, no flash yet, but it could be coming}
08) camera {video, iso, white bal, flash}
09) tklock-both {power button unlocks lockscreen + homescreen}
10) things i compile in scratchbox
11) locally&remotely executable terminal commands to:
+customize launcher-buttons on home screen
+change profiles {silent/meeting/general}
+(un)lock lock/home screens {simulate power-btn short, long, and double press}
