The Nokia Prism phones are very different to the average mobile handset in their design, the exterior has been diamond cut to leave a 3D triangular pattern across the face of the phones and even the buttons are made up of triangles.
The first of the range to be released was the Nokia 7500, a 2.0 megapixel camera phone in candy-bar format that did not break the budget but stood out in a crowd, this has now been joined by a new and final addition to the Prism range, the new Nokia 7900 Prism.
The new model offers similar design, specifications and features but there are some tell tale givaways that need to be addressed, firstly the exterior design has been altered slightly by almost flattening the top of the handset to leave two distinct corners rather than the rounded edges of the 7500 and there is also the addition of a new silver diamond menu navigational key just below the main screen that was colour coded on the 7500.
The rear of the 7900 is manufactured from different materials that the 7500, it is made from a black anodised aluminium first seen in the Nokia 6500 Classic which gives the handset a sense of expense and worth.
Both models offer a 2.0 megapixel camera with a flash for low light conditions, a digital zoom for close up photography and support for short video clip recording and playback, strangely, although the new 7900 Prism is a 3G enabled device it does not offer a secondary camera for video calling but instead uses the technology for faster download speeds and multimedia content access.
Being 3G enabled opens up a wealth of new media such as the latest new and sports headlines streamed to the handset, new movie trailers before release and access to the newest music videos, it also allows for fast download of new mobile content including ringtones, games, themes and wallpapers as well as new music tracks. The Nokia 7900 has a built-in MP3 player which can also be filled with songs directly from a PC using a mini USB before being organised into playlists to suit genre, mood and tempo.
To store the photo, music and video files created with the device there is a substantial 1GB of internal memory
The main display of this new model has also been upgraded to a OLED screen that supports 16million colours rather than the more traditional TFT LED displays, which then continues down the phone and shines through the keypad - low on battery, signal strength or loss of daylight and the display colours change to signify the changes in conditions, there are also lights to signify missed calls and messages.
Other standard features include GSM/GPRS/EDGE, Bluetooth 2.0, microUSB, web browser, email access, built-in handsfree and downloadable games, the list just goes on.
Some may say that the Nokia 7900 is strange looking slightly odd handset and some may say that its stunning in every way, but one thing is for sure it is unique in its intriguing bold design and intelligent in its capacity as a mobile phone.
