Will there be any one feature that the Iphone 6 has that will prevent you from buying it? I have been racking my brain trying to figure it out. It certainly looks like the screen size ( 4.7 or 5.5 ) will be adequate. If the resolution of the phone is not at least close to 1080P ( rumors of 1704x960 ), that might do it, but Apple has been very good with color accuracy, viewing angles and brightness. If the battery is proven to be less than stellar, is that a deal breaker? Apple will probably make sure that the combination of battery size and resolution get us through a full day without a charge. IOS has worked well for me in the past and IOS 8 will probably be fine. I think the only real deal breaker for me would be the size of the 5.5 inch phone. It could be monster big, compared to other phones.
