"To compare or not to compare? That is the question." Nokia has protested many times that the 5800 XpressMusic is not an iPhone competitor, but rather a lower-priced alternative - and I agree in this detailed editorial over at All About iPhone. There's no doubting that the 5800 was influenced by Apple's flagship, but the differences in functionality and emphasis run pretty deep, as is obvious as I run through each device's strengths and weaknesses.
