10 hours running, no less on ram than i had when i started. Created some ringtones on it from mp3's, listened to mussic for a while, set up my bluetooth device, browsed the web, etc. No issues. No crashing. No memory leaks that i even had with wm5. This is actually running better than wm5 did for me, by far. I think it might be due to the fact that the 6700 has 200mhz faster chip tahn the 6800, but i'm not sure.
