So, bought a N8.

It does indeed work with an N900 in Mass Memory setting. This is awesome.

Happy about the phone, too. Symbian^3 isnt s60v5, thank god. That was my biggest fear.

Anyways: nice. usb otg rocks. now I can use my tablet for torrents and **** at home and just usb it to my n8 if needed. Perfectemundo.
