I haven't cancelled my cellphone plan yet, so I'm using the N900 completely without cellphone functionality. And I can tell you, there's so much to keep me occupied, I never even think of it (until I take my old cellphone out of my pocket to make a cal, that is...).

I would receommend it. It really is like a portable computer. I haven't even begun to scratch the surface of all the things I intend to do with it. And with 32 GB installed memory, you can carry a lot around with you thast you'd normally be streaming.

Also, I think some of the offline maps are amazing, so there's even that.
