Sony Ericsson Vivaz Pro, the slide-out keyboard is a major element, Sony Ericsson have managed to retain the good looks of the "original" handset, adding just 2mm in thickness and 20 grams in weight. But for some unfathomable reason, the camera on the Vivaz Pro has been downgraded to a 5 megapixel one from an 8 in the Vivaz.almost everything else is identical to the standard Vivaz including the rather lovely 3.2" 360 x 640 pixel touchscreen display, 3.5G and WiFi connectivity, Bluetooth, microSD expandable memory (with 8GB included in the standard sales package) and a FM radio.
