I use my iPhone 4S for occasional photography - for a 3-year old model, it's not too shabby, particularly using HDR. Only downside is that I have to use f**king iPhoto on the Mac currently, and iCloud syncing sucks donkey gonads. Looking at alternative ways to get photos off of my phone. I'd be interested in finding out how other people are using their phones for photography.
I recently got iMazing (available for Windows and OS X) which does a great job of letting me transfer music and movies to my iPad. So I no longer need to suffer the abomination that is modern iTunes. Might start using that with the iPhone to retrieve photos, in which case I can turn of iCloud syncing.
I've actually resorted to emailing photos to myself a few times, because iCloud was taking its sweet time as usual.
I'm interested in a droid group. I think an iphone group already exists (but I have no idea)... I take a lot of pictures with my android, but I rarely make them artistic or take them for art's sake, so I'm not sure how active I would end up being.
