Of course IOS has a LOT to offer. So does Android. Anyone that claims one platform has nothing or little to offer is simply chest beating/in denial - or is just obtuse.
Both platforms are great. And both the iPhone and several Android handsets are great too.
I know people get heated about sports teams - and also other things. But, for example - I don't (or I haven't experienced) such polarity/behavior on the photography forums. Are there people that swear by Nikon/Canon/etc (and have strong opinions) - sure - but typically - people state the obvious - use what's best for you and for your use case. I don't think I've ever read where one "side" says the other manufacturer's devices suck, are crap, worthless, hope they fail, etc. Funny.
