To make the cursor appear just replace the cursor icon file (transp) in /usr/share/icons/default/cursors with one that shows up.
An entry in xorg.conf needs to be added to fix sensitivity.
I have no idea why this was disabled on release.

joerg_rw deduced from the schematics and the drivers that OTG was removed due to USB.org cert issues, it was a last minute thing, OTG was planned for the N900 from the start, but I guess due to people *****ing about delays they swapped USB ports and killed OTG.

Anyways, these are my opinions, as a previous Symbian user I can say the N8 won't bring me back to Symbian, and nor will Symbian^3.
