OP, you will be far from the only one.
There's a ton of people here who imagine the 5.5" is gargantuan- the "why don't you just get an iPad Mini?" crowd and similar. All it takes is a tape measure, pen, paper and some scissors to scientifically shift from imagination to reality. In hand, a 5.5" is only 1cm wider and only 2cm taller than a 4.7"… but it comes with a .8" bigger screen and several other benefits.
Pre-launch, there were polls that implied the split would be about 70:30 favoring the 4.7". However, once people can actually see both sizes, I suspect that's going to shift. "We" are much accustomed to 4", so 4.7" is huge and 5.5" is beyond huge. But we're only accustomed to 4" because Apple hung there for so long. There's a world of people who have been exposed to phones bigger than 6". From their perspective, 5.5" will seem small and 4.7" may seem too small. Our perspectives will evolve now that Apple has endorsed 2 new "perfect" sizes and especially after they are in stores where they can be held in our own hands.
I suspect there will be a lot of "but then I got to see one" and "it's kind of growing on me" posts & threads over the next few days & weeks.
