Yesterday (Friday 11 Jan), my Wife and I went into Dick Smith in Porirua to have a close look at the 32" FHD Vivo to compare it with other sets. We were hopeful as the paper specs look very good. So I'm sorry to have to report that we were disappointed with the image clarity when seen side by side with several other TVs playing the same HD material from a USB stick. We found the picture of the Vivo to be not as sharp, the colours washed out, and the image relatively pixilated. This is in comparison with an HD (not full HD) Samsung, a Panasonic, and another full HD Samsung.
In the end we purchased a relatively new Samsung HD Led TV model UA32EH4003M (not from Dick Smith) after comparing this with a very similar Full HD Samsung Model and several others. We felt that the perceptual difference between the HD and FHD Samsung models (playing HD Blueray material) was apparent only very close up, not worth the significant extra cost, particularly as for us this TV is a secondary one for use in an exercise room.
With some negotiation, based on the Dick Smith sale price for the Samsung ($449 + $40 gift card), the cost of the UA32EH4003M was almost the same as the Vivo. We didn't purchase from Dick Smith because we have had horrible experiences with their warranties, so now shy away from making any substantial purchase from the store, certainly avoiding anything above their current replacement policy cutoff of $400.
By the way, on setting up the TV I was pleasantly surprised to discover that the Samsung supports an optional high speed WiFi USB dongle for network connection. So I now need to get one, available for around NZ$60 from ebay including shipping (or $99 from Dick Smith!). Or, here's an article on adapting other types of Ralink based n wifi dongles: http://wiki.samygo.tv/index.php5/Using_NoN-Samsung_USB_WiFi_dongles_with_TV
