Sony Ericsson Vivaz Pro Symbian smartphone

Symbian S60 is back as the operating system along with its five home pages that you can brush between or select from the menu bar at the top of the screen. There's a blank screen, plus another for contacts, pics, shortcuts and a Twitter feed. There's a Facebook app on-board, but it's not included in the home screen menu. That's a shame, as is the inability to pull in your contact details from either Facebook or Twitter.

The Pro's 720MHz CPU lacks welly

There's a 720MHz processor inside the Vivaz Pro, but it doesn't seem to be quite up to the demands placed on it by the OS and the UI.

Call quality is OK, if a little on the quiet side, but the keypad at least features large keys, which unlike many aspects of the menus, are generally easy to hit. Battery life is OK but not outstanding - it delivered a little under a day and a half of fairly heavy use.

The browser hasn't improved since the last incarnation, with its ugly menu bar and a whole series of usability irritations, like its slow pace even over Wi-Fi, the insensitivity of the screen making it difficult to hit links, the awkward zoom function, and the lack of text reflow when you do zoom so you end up having to scroll across to read text.

The camera has a lower resolution than the Vivaz

The browser has Flash Lite, so you can view YouTube in full screen, but no BBC iPlayer, for instance, despite the presence of an iPlayer app in the menu. It all adds up to a distinctly sub-par browsing experience.
