The first thing I noticed when unpacking, but the relatively large weight. At first glance, anyway. On the second, it does not bother so, since one has something in his hand and a full keyboard is integrated. The mobile phone is the 5800 associate in size, is the same, only slightly thicker. The integrated keyboard is great for SMS and prolific writer a boon. The mobile phone can be postponed easily. The gap dimensions are good, workmanship excellent. However, the keyboard starts up normally. If you have the phone in front of him then, it wobbles when writing imemr slightly forward. Here I would have liked an obliquely upstanding screen as N97.
The display is easy to read and very light (adjustable). The display rotates relatively quickly when set. When sliding the display always turns to landscape, even if the rotation of the display is turned off.
The window viewing reacts sometimes a bit sluggish and only after a few moments. The touch screen is a resistive, which responds to pressure, not on mere touch as the X6. Getting used to the operation in the corners. If you want to change in the landscape as the profile and is the selected bottom, happens when you press first nothing. Here you have to press a little above the signature, then you go. But you get used to it.
What I do not want to get used to this: Is not active the key lock, you need the 5800 or the X6 only briefly to stroke the display, then the monitor reacts with turning. That can not be the C6. You have to press a button for the monitor is illuminated. But that's like anything habituation thing.
Very nice enjoyed the LED around the charging port for power supply. This lights up when the phone is being charged; when it is full, the LED goes out. So you always see from afar, if the mobile phone is still charging or is already full.
Call quality is excellent. Slightly lighter than at X6 or 5800, which are about baßlastig, but clearer and easier to understand. Landline similar. The endurance is good. Ca 4-5 days you can hold out during normal operation. The reception quality is also good to very good. In my apartment I usually only get with Vodafone network, here it works well with T-Mobile, although weak reception.
Very nice also that the Benachrichtungs LED has been retained. Although this is less illuminated than in 5800, but still visible. For missed calls or SMS these flashes quickly, during normal operation slowly (can be disabled). To release the battery cover is incidentally also a boon. Pull switch down, you can already put it on without effort.
Conclusion: For the price and also has a total of a very successful Nokia mobile phone that is easy to use, good endurance and above all excellent voice quality. Plus there's a full keyboard. Since you can not go wrong.
Addendum 20/11/2010 - Meanwhile, the mobile phone has repeatedly turned off and could only be "revived" by removing and re-inserting the battery again. As via the Forum, this device is probably not as well done as initially thought.
