...exclusive design and materials with nice functionality.
The Nokia 6600 fold is considered the flagship of the trio at least according to Nokia. The clamshell offers a one-click electromagnetic opening mechanism with dampened hinge for smooth motion and flaunts an unusual combination of material such as the smooth back and the high-gloss front.
The Nokia 6600 fold has a QVGA 2.13-inch 16M color OLED display and a 2 megapixel camera with dual-LED flash. Thanks to the built-in accelerometer, a double tap on the Nokia 6600 slide can snooze an alert, silence or reject a call or simply wake up the hidden external 128 x 160 pixel display in order to visualize the clock. The Nokia Arte had a similar functionality but there it was limited to only displaying the clock.
In terms of network connectivity, the Nokia 6600 fold is able to offer quad-band GSM/GPRS/EDGE support plus dual-band UMTS support with video calls. The device is based on the Nokia Series 40 user interface and will have support for microSD memory cards with a capacity of up to 4GB.
The Nokia 6600 slide builds on the same well-known name but again doesn't offer the smartphone functionality of the original Nokia 6600. The new slider has the same double tap feature of the 6600 fold and also has some interesting materials used such as glossy surfaces and steel covers.
The Nokia 6600 slide is again based on the S40 user interface and has a QVGA 2.2-inch 16M color TFT display. In the same time it remains compact enough. The 3.2 megapixel auto focus camera is also capable of recording VGA resolution video clips at 15fps (in 3GP format). The Nokia 6600 slide also has a FM radio and some dedicated music keys.
Connectivity features include quad-band GSM/GPRS/EDGE support and dual-band UMTS with video calls, Bluetooth and a microUSB connectivity port.
Last of the bunch, the Nokia 3600 slide also has some neat features in store for would-be owners. Its sliding body again has some high-gloss surfaces with gradated colors, metallic elements and soft ceramic paint. Beside the 2.2-inch QVGA 16M color TFT display, the 3600 slide also boasts a 3.2 megapixel auto focus camera capable of capturing VGA MPEG4 videos at 15 fps and a two-step camera key.
