The 810's display is reasonably large measuring 2.2 inches diagonally, and I have to say that I really don't take to Vodafone's standard theme. However, there is a black backgrounded offering on the handset you can switch to that looks a little nicer, and you can download more themes, of course.
I've mentioned that this is a 3G handset. It also functions on the 900, 1800 and 1900 GSM bands - i.e. it is tri-band GSM. It has a Web browser which works fast enough over 3G but is lacking in features. For instance, I'd have liked the options to zoom out in order to see more of a page at once, and to push the screen into wide format.
The long and the short of it is that Vodafone needs to work on its built in browser, or simply do a deal with Opera and pre-install Opera Mini if it really wants people to use the browser seriously. With the latter so widely regarded and popular this might be a good route for Vodafone to take.
There is a front-facing camera for video calling and a back-facing 2-megapixel camera for shooting your own stills and video. The lens is on the outside of the casing rather than being protected by the slide. The advantage is that thanks to the side mounted camera button you can shoot photos without opening the slide. But the disadvantage is that the lens is vulnerable to scratches.
Now, 2-megapixels isn't enough to set the world on fire, camera-wise, and with no flash your indoor options are rather limited. My sample indoor photo of the coloured dish taken under normal household lighting conditions is a little less vibrant than I'd like.
As for outdoors, many of my test shots were taken in bright sunny conditions with strong highlights that really stretched the camera. The chair, which has recently become a standard outdoor shot, is a little flat, whereas the portions not in the shade are completely blown out. The white flowers were photographed in a shadier spot, and although colour reproduction is reasonably accurate, the overall picture is very soft.
