The Nokia 6600 is a great phone with functionality packed to the top. A large colour screen at high resolution. Exceptionally good quality built-in camera with 2X Optical zoom. Includes most functions offered by a hand held PDA. User friendly interface (A Nokia Speciality). Customizable fields in the contacts phone book to add or remove exta details. Web browsing is enjoyable due to the large screen. Bluetooth enabled and sync with PC is no problem and there is no need for data cable.
Easily recognises other devices via Bluetooth (tried with PC, Sony6110 & XDA) Speaker phone facility is ver handy. If that was not enough it also records videos and playback is very good. Videos can be stored on the provided memory card (32Mb) however that can later be upgraded to up to 1Gb. hours of fun. Some good games available such as PinBall & good old (or New) Snake.
If you are use to tiny phones such as Nokia 8310 or Semines SL55 then you will find this phone a hand full i.e. in size but you get use to it after a while. Its not that much heavier weighing at 125g. Overall a great phone especially if you need to sync with PC contact and keep track of your appointments etc.
