It was in March that I reviewed the 7900 Prism from Nokia. That had followed a review last year of the 7500 Prism. Both were similar in design with a diamond-cut approach to the fascia and a gem-like take on screen themes.
The diamond cut fascia idea has recently reasserted itself in the unlikely shape of HTC's Touch Diamond and Nokia has resurrected the Prism range with the 7900 Crystal Prism.
The 7900 Crystal Prism is one of those mobiles that falls into the more style than substance category. Which is fine if you like the style and don't mind the lack of substance.
In this case the style comes in many guises. First off there is the diamond cut patterning of the phone. This runs to shaping on the front fascia which puts all the number keys into triangular buttons that between them form a sort of diamond pattern. The Call, End and softmenu keys aren't triangles or diamonds, but aren't rectangular either.
Then there is the styling of the back panel. A pink horror set against the shiny blackness that comprises much of the rest of the fascia, this piece of aluminium has an etched pattern on it, produced with the help of creative designer Frédérique Daubal. Nokia has ruined whatever subtlety the design might have had by stamping its name in there.
Next, check out the navigation button on the front of the handset. Its select button is a crystal. The crystal is pink and I am not sure what exactly it is, but it doesn't look too classy to me.
