iPhone worth it?

[Aspect]

Is the iPhone worth having without the o2 contract? I know the o2 contracts come with the unlimited data, but with my contract it would cost me a fortune to do that stuff so i just wouldn't bother.

Would i be missing out?

Im just a sucker for shiny stuff, every time i pass an o2 store i keep drooling. I really want one, but im worried that if i dont have the o2 contact i wont be getting the "iphone" experience as it were.

I take it you guys dont think its the case.

I don't think my contract has any data as part of it. Shame i haven't had my current phone for long. I may wait for a while then get one.
