We do quite like it being slightly bigger oh and sorry forgot to say...we didn't go for the plus bigger model as we felt it was just to big, or more to the point would not fit on my belt clip! design is great and being slightly thinner than the iPhone 5 is great, although I wouldn't actually want it any thinner "apple take note" and I see that quite a few are popping up on the internet, which have had bent cases! Obviously it's fast as you would expect from a 64bit architecture phone! and even though it was pre installed with the new iOS 8 apple operating system it still felt very similar and easy to use just like its little brother. Actually at first struggled to find the new features but the new "tips app" soon put that right and was a very good idea on apples part :-) also the on off button has now moved to the side and this seems awkward and unfamiliar "I guess we will get used to it" but hay why move it in the first place! Not sure how strong its going to be, time will tell I'm sure! but it definitely is a quality product just as what you would expect from apple.
So far basically overall we love it, battery seems good and it does what it supposed to do "perfect" just really looking forward to bringing it all together with the iWatch :-) its really disappointing that production couldn't be completed before Christmas, but hay there you go "all good things come to those who wait" right!
