Depends if you want a touchscreen mobile or not. I just got my hands on an N86 8MP (for an absolute bargain price I might add) and it's basically an upgrade of the N95 8GB. I am in the same position as yourself in that I have an ipod touch so therefore really no need for an iphone and the touch always seems a tad gimmicky to me anyway.
Anyway, the camera is the best I have seen on a mobile and the build quality is significantly better than the N95 8GB (although admittedly it is slightly heavier). I like the familiarity of a nokia and the fact that I can just reinstall all my old applications and use it exactly like my old one. If my N95 had not broken then I wouldn't have swapped but being honest I am glad I did. The screen is brighter and the keypad is easier to use. If I were you then that is the one I would get. With an ipod touch it really is the best of both worlds.
