After using the N8 with symbian Anna, I would have to say, it has so far been rather smooth as compared to how my i8910 S60 V5 runs. The gallery with over 1000 items, music, video runs nicely.
I miss the stereo speakers & sound effects though.
It would be interesting to see what nokia can do with windows, open mind. I still enjoy the symbian experience, but getting an N8 with bigger screen, better cpu/ram, the e7's keyboard is nice, but lacking the xenon flash / microsd slot, i could live with an 8mp cam, fm transmitter on the n8 is nice.
Dab radio would be interesting to use but the headset @ £40 is a bit much.
The N9 & N800, it would be good for someone to compare!
