A success story for a change... ssu update wwent well for my n800, both on flash as on sd, even though I had removed the pdfs etc from my homedir, and off courrse had to reinstall bootmenu twicce.

The good: button hang seems fixed
The bad : videocenter does not seem to work, and less stable overall(full tablet crashes every 2 days, and desktop crash almost daily.

Overall, the best version of os2008 for my n800 yet (Chinook was terrible). Kudos to nokia for the shorter time to fix.
