Have this phone now for almost 1 1/2 years in continuous operation. I had quite a few phones in my life, but the Nokia 6300 is one of the best. I use my phone really just to make phone calls and writing text messages, so voice quality and battery life for me are the most important criteria. The voice quality is 1a and my battery will last even after 1 1/2 years, is still a good week through. But I must confess that I am not a frequent callers. Also, the device is very robust and has already survived several falls on the floor.
What also is important to me: With a corresponding, freely available on the Internet Plug-in can synchronize with Mac computers the phone without difficulty via iSync !!
For camera and MP3 capability, etc. I can not say anything because I do not or rarely use these functions.
But if just a cell phone with no frills want, with whom he telephoned primarily will be well served with the Nokia 6300.
