Eh. I'm not chomping at the bit for the 5, but my boyfriend really wants one and will probably get one as soon as he can.
I just got a 4s a few months ago and there's nothing on the 5 that seems revolutionary enough for me to discard my 4s and pay upwards of 700 bucks for the 5. If it's faster, cool, but I don't have issues with my 4s.
I'm not really an apple fangirl and will likely never own an apple computer (I think they're way overpriced for the quality) but I seriously adore my ipods and my iphone has been equally lovely. I liked some of the android phones I messed around with, but none of them were as nice (to me) as the 4s that I got for the same price.
