I do all of the above on a Iphone 4s as well. That is a problem I have with almost all digital cameras, aside from a DSLR--taking a lot of shots fast.
Until Apple bans something you like. Maybe because they think it is offensive, or maybe just because it is competing with one of their own apps. You never have to worry about this on Android, because all Android phones can sideload apps, or use alt App markets (and without jailbreaking...all Android phones have this capability by design). Google does not try to hold you hostage to one app store. These are not the only examples. And none of these would have been banned on Google's app store. Not even iOS-specific stuff. Even if it was, you could easily sideload it, without having to jailbreak, and Google would do nothing to stop you. - - - Updated - - - You got what you paid for. Like I said, if you don't care about the extra functionality, I agree it would be stupid to pay more money. But the people who pay more do get more.
