Ehh. I like that people can take better pictures but the biggest thing i'd lose is the personality of my 35mm f1.4 - it has a character that makes my pictures feel more lively to me. But always nice to have a better camera for Instagram quick pics! If only the photos app wasn't an unorganized heap of pictures of travels, receipts, and other documents..
So true, the Camera Roll gets quite a mess with time because all types of pics go to the same place. Fortunately, there's already a solution to that. With an additional, complementary photo library like the Utiful app one can cleanly divide the family and vacation photos from the receipts, screenshots, etc.
