"It's slightly faster, it's got a slightly better battery and it's in a different colour - and I'm sorry, but colours don't scream technical innovation.
"We ended up with the app store, with music on your phone ... it suddenly became all things to all people and it's very hard to live up to that.
"I'm sure they'll sell really well - they are still selling really well - but it's getting harder and harder to completely change things, and I think we've kind of reached that plateau now where everyone just says, yes, it's an iPhone, I know what that does."
Technology commentator Peter Griffin also said much about the new product was "just incremental change you'd expect".
But he was interested to see how the fingerprint scanner would be received.
"That's never worked on a mass scale before and if they can make that work, it's going to be a massive game changer."
Mac.nz founder Mark Webster believed the new product would be well recieved by Apple fans.
"And for people who are just looking for innovation and excitement ... they are not going to be happy. I just want to know what people expect these days. What do you want, anti-gravity? I mean, it's a phone."
