My first impression is, does more mpegapixel instantly make the Nokia Lumia 1020 a better phone? If you truly want to take good photos, use a real camera, like a DSLR. Admittedly, 41-megapixel is quite a wow factor, but based on the hardware specs it seems it's more of a camera than a phone. The other questions is, do people want to every photo to be 20MB+?
The article does a really bad job of explaining what's going on here- the resulting photos won't be 41megapixels. It uses that huge amount as a means to "smooth out" the noise/oddities in the photo, and save it as a more reasonable 5MP or 8MP image.
Presumably the individual pixel size is smaller though? So where's the true advantage here vs having fewer larger pixels which would presumably have less noise anyway.
