I actually admit to being a hypocrite, but let me explain myself.
I've always wanted to own an iPhone since its release in 2007, but I never wanted to spend the money to get one, so I eventually got an iPod touch 4G and then an iPod touch 5G and I used a regular cell phone besides it that didn't do anything except making calls and sending texts. Since I owned an iPod touch, I had to be on Wi-Fi most of the time since naturally it doesn't feature cellular data.
I knew that the end of the iPod touch would come soon so I decided to buy the next iPhone to come out, which turned out to be the iPhone 6. When I first saw the leaks I was disappointed that the screen/phone got bigger, I never wanted to have a huge phone, I hated huge phones so much because at the time I thought they were pointless, however, I was impressed with the design of the hardware, it seemed like a mixture of iPod touch 5G (that I loved so much) and the iPhone 2G. I ordered the iPhone 6 anyway because I don't do Android or Windows, so the only choice left was an iPhone. Also, I wanted to own the latest hardware possible so I can enjoy my iPhone as long as possible before being forced to upgrade, hence the purchase of the iPhone 6, not caring about screen size at all.
Before the arrival of my iPhone 6 I was worried about the screen a lot and when I unpacked it I was shocked about the actual size compared to the iPod touch 5G, nonetheless I got used to it very quickly and I can't imagine going back. When I use the iPod touch now, I can't believe how SMALL the device actually is.
I do believe 4.7" is the limit for me, personally. The iPhone 6 is, in fact, very big compared to previous models and I really couldn't imagine getting an even bigger screen (looking at you iPhone 6+), yikes. I still don't see the point of big phones, even of 4.7".
I'm in a love-hate relationship with my iPhone right now: I think the screen is amazing, there's so much space for content but at the same time it makes using the phone one-handed a mess, even with Reachability. I really do hope that the minimal size of the iPhone will never get bigger than 4.7" and honestly, if there were a 4.0" option available I would have still gone for the 4.7" phone, even though I'm not really a fan of big screens.
