Loosely fashion relevant: I'll be curious to see how many people pony up for the 18k gold Apple Watch.
Don't know about the watch (seems like a waste when you already have the phone in your pocket) but I am definitely pre-ordering the non huge 4.7 model. My 5 is crapped out since I don't believe in cases
I might buy a normal sized 6 whenever my 5S inevitably craps out on me. I haven't had the best track record with my iPhones (on my 4th in 12 months) because I don't use a case (dropped it and shattered once on accident, once because my girlfriend swatted it out of my hand while I was getting an Uber outside of the bar, and once when I jumped into a pool in the Bahamas with my phone in my pocket), so odds are pretty good that I'll have a 6 in my pocket some time in the not so distant future.
The 6 Plus looks way too big for me. I'm not particularly happy about the 6 being bigger than the 5S, because I thought that 4S/4/3G/OG iPhone were the perfect size, but the 6 is as close as I'll get to that size and still have the most recent tech in my pocket.
