Elegant part with weaknesses

I have a lighter and more elegant replacement for my clamshell phone Nokia sought in the 3710 7510 Supernova and 6267. My comparison refers to these models.

+ Light, suitable for the shirt pocket
+ Is through the grip battery cover still well in hand
+ Looks really elegant
+ Better screen representation
+ Better camera
+ Navifunktion, (not rated)

- Keyboard is not as good and pleasant to use as the comparison models
- Tinny sound at the transmitting and the receiving side
- Ancillary and road noise, as a passenger, of course :-) ', clearly and audibly distracting
- Weak GSM reception or transmission performance with choppy transmission
- Impression of the keyboard on the display no longer be removed later
- Front side is a fingerprint magnet
- The opening of the battery cover is easy, but when you close the cancel something you actually fear or damage
- Data cables must, despite the price, be purchased separately

The acoustics, the keyboard and transmission in low GSM network are a step backwards for me.
