I actually wonder if its worth it to do a search on the forums and find all the "nokia is dead" posts. Guess its not because people will always say that and think that Nokia=Symbian.
The new Series40 phones look very good, as does the Windows Phones ones. Personally I think my next phone will be the 701 running Symbian^3 Belle. The UI is much better looking and more fluid than Android or iPhone and its a proven platform.
I've been a Nokia fan for many years, but I really think they need to pick a strategy and stick to it. All the symbian/bella/meego/windows mobile changes have deterred me from making my next choice Nokia. I really think they're about 6 months too late with these new phones.
To be honest, I dont know if Nokia would be the "Big thing" Windows Phone was hoping for, its just another Windows Phone with navigation. Personally I would prefer the N9 vs the 800 as the N9 has a bigger screen, more ram and a much better OS also N9 with 64 gig would kick butt.
