I'd like to agree with you but I can't really because that argument comes in the same kind of logic that more megapixels = better camera.
Sure it is nice to have the option of a flash, I can't argue with that, but there are plenty of phones out there with flash that would take much worse pictures than some phones without flash.
I'm not saying that people are wrong to like flash on phones, I'm just saying that to discount the most powerful feature rich android phone to come to the UK because it doesn't have a flash on the camera is a little strange.
Also I've been taking night indoor photos with no flash for years and they come out ok.
With your phone? I doubt that very much tbh. I am very impulsive and just like to randomly snap things. Even silly antics in a pub. I can't be bothered with poses ect and do not carry a real camera with me. No flash would not work in this scenario with a phone due to the exposure times and grainyness like I have already mentioned.
Its my preference above having a graphics chip for games that don't exist on Android yet. When they do I will no doubt be looking at more powerful phones anyway.
