I have owned the K790i for about 6 months and now i own a N93, and i can assure you that its a no contest between K790i and N Series phones as far as picture quality is concerned, as someone mentioned there is too much of picture processing in N73 which for some1 like me takes away the photo quality, what it does is remove the grains in the picture by post processing which also takes away the detail, however the lens in SE is of better quality and shows more detail and there is not much post processing, plus the Xeon light on SE takes it a league apart in low light condition, you may think that you dont get into low light condition, but believe me that you will, like in a party or a disco...the N73 LED is simply not capable enuf.
