I'm an iPhone guy, don't really compare specs. Most of the time I have an incredibly difficult time seeing the speed difference between the 4S and 5. So in real world how would a phone that is in between them in performance be all that earth shattering?
This is as silly as when the S3 was trumping the older 4S. I'm sure a couple months from now there will be a faster Android phone out and we will have to hear about that and the cycle will continue.
what that means is the iphone 5's processor uses significantly less battery for the same or better performance. that means it can be thinner and lighter, and still run as long. differences between the 4s and 5 are easy to see when multitasking, or in battery life. my iphone 5 lasts significantly longer than my 4s did. enough that i don't need to worry about it at all for a day. that's a pretty big improvement to me.
if i were using an android phone, it would have to be much bigger and heavier to get through the same usage. i'm very much enjoying not having an awkward bulge in my pants all day. androids will soon start shipping with a15 based SOCs. while it will improve performance over the iphone 5, it's a server oriented chip that's going to be even bigger and hungrier.
