Have my N810 for a week now.

Good things: wifi and GPS. Numerous third-party apps.

Gripes: slow device. No support for flac and ogg out-of-the-box. Very bad email app, very bad contact app (pretty useless in fact), no MSN support, poor quality of the GPS apps.

In fact, the device by itself is okay but the default apps are horrid and slow.

Though, I still love my N810
