Well I have both the Nokia N8 and Nokia N900..

Here are the things which I personally like about the N8:
OVI Maps
Superb Camera
Capacitive Screen with 'Pinch-to-zoom'
USB on the Go
the numerous apps from OVI store
knowing that Nokia won't stop supporting you in terms of updates etc.


However, I really miss the hardware keyboard which is present on my N900 and the open-ness of Maemo.

Also, Symbian feels kinda weird on a touch-screen device (in my opinion Maemo is the ideal OS for touch-screen phones).

But overall, I am happy with both devices. I would never sell either of them.
