Is ios stale?

I really want to get a iphone but ir being "boring" or "stale" is holding me back. I was about to buy one but a couple of my friends told me not to do it. From what i hear the os is "boring" or something like that. I really haven't had that much hands on with ios. I could tell you everything about it but besides playing a game on a ipod touch and ipad I haven't really touched it.
