I think it depends on the purpose of taking the photo but for me as an amateur, it's about having a certain level of enjoyment from the whole process rather than getting the purest image quality I can. I do have mixed feelings about the old saying that the best camera is the one you have with you. For example, I don't get out by myself specifically to take photos as much as I used to do and if I happened to be on a day out with my other half she would often get fed up of me stopping to compose several shots and change settings on my dslr, plus it would often take up room in the family rucksack. As a result I often just relied on my phone camera but it left me feeling underwhelmed by the lack of focal length or resolution etc. so I have just upgraded my phone in the hope of reaching a "better" compromise. I haven't had chance to test that theory yet but with a bit of luck I will do so this weekend. Also, carrying a dedicated camera can make you feel a bit conspicuous in certain situations.
