It entirely depends on what you get, and currently have. For example what if you do have a decent enough phone? Then you can generally get a Gaming PC since you have a decent, functioning phone. However if you have a decent computer then simply buy the Iphone 6 is you don't have a good phone.
Through my personal opinion, I don't really see the relevance of an apple phone. Especially when it is seemingly overpriced, as well as its purpose and use being very standard. But the cool thing about an Iphone 6 is that it bends. Avatar, the last phone-bender. *Ahem*
You should definitely make the product you buy to have a good purpose of use, not because it is some sort of trend, or looks pretty and famous, but it works well and helps you out as well. And I think you should go ahead and buy a really good phone, maybe a Nokia Lumia? C:
