(sorry, can't post links yet, but just google for 'office android tablet', there is a lot of information released on news sites in the last 24 hours.)
Unfortunately, the preview sign-up says they are only supporting tablets 7" - 10.1"
I tried signing up for a preview and chose 10.1" but when it asked for the tablet model I chose other and typed in "Samsung Galaxy Note Pro"... I guess I might get rejected
Can anyone share their experiences if they've been able to get the preview running on the Note Pro?
