I remember back in summer of 2010, I saw a high school teenage girl hold an HTC Evo 4G, and my first thought was how large that phone was. At 4.3 inches, it was gigantic for its time. Yet, the phone was actually 2mm shorter than the iPhone 5 but wider and thicker. As late as 2013 when I was still going through my transitional phase with a 4.7" M7, I thought the iPhone 4/Nexus One were the perfect size for one-handed use except I came to realize that I don't use one hand when I browse or text. Even when I had a BlackBerry QWERTY phone like the Bold 9000, I still held it with two hands to text.
Now I have a 5" Mi 3 with similar dimensions of the M9, and when I went back trying an iPhone 3Gs last week just for kicks, I literally had to do a double take on how small it was compared next to my Xiaomi. I just gave it back to my Stepfather after a day. Screen was blurry, laggy, crashes, etc. Harder to text and remember when the first iPhone 2G came out, it took some time getting used to typing on it since the screen was so narrow and we couldn't turn off the stupid autocorrect until iOS3. Imagine it was only a few years ago where my ideal screen size was 3.5-4.3" and to see how quickly it changed once I got used to using a larger display after a couple years.
I believe 6" should be max though just like we rarely see anymore screens under 4". I don't have any holster case to fit an Asus Fonepad 7. As big I can go is Huawei Ascend Mate7/Nexus 6. Between iPhones, I pick the Plus version every single time unless I need a backup and the iPhone 6 would be nice to use on certain occasions when you want to carry it in your pocket.
