i understand and agree with what you guys are saying. For me though if I'm not going somewhere specifically to take pictures then it's not too big of a deal if the hue is a little off or if I have a 5 or an 8 megapixle camera because i'm probably not going to be shooting for any billboards anytime soon. just saying.
May have just been the pictures I was looking at, but on a standard 15" computer screen you can see some resolution differences between the 5mp and 8mp. Probably not much (and may just be my imagination), but I think photos are just as likely to be transferred and viewed on a computer as the phone. In many cases you might occasionally view them on larger screens like a desktop monitor or a big screen tv - the latter case the 8mp might not look great but the 5mp would be pretty awful. Also, if you want to crop and enlarge a portion of the photo the 8mp will, again, make a difference.
Just because a phone might suffice when superior quality isn't overly needed doesn't mean there isn't a minimal acceptable level, which is where I think a lot of people are hung-up on the Nexus camera.
