David Gilson and I play tag team reviewer for our coverage of Sony Ericsson's Vivaz range. Having tackled the Vivaz, I hand over to David for the Vivaz Pro - in this, part 1 of a two part review special, he examines the Vivaz Pro's hardware in detail and runs it heavily for an intensive week of duty. Despite an appealing design generally, David was very disappointed by the battery life and felt a bit let down by the output from the 5mp stills and 720p-recording video cameras

"The Vivaz Pro is the latest Symbian offering from Sony Ericsson. Back in March, Steve reviewed the Vivaz (see parts: one, two, three, & four) and he found that it had delightful hardware but that the software suite was let down by an inconsistent user experience. Moving forward, the Vivaz Pro offers a slide out QWERTY keyboard, a lower resolution camera, and a leaner set of software.

Read on to find out whether the physical keyboard improves the Vivaz's usability and whether Sony Ericsson have managed to create a cohesive S60 user experience."
