This is an interesting opinion to me. My background:
I had a "dumb phone" until Sept. 2012 when I bought myself an iPhone 5 as my first smartphone. I'm a large guy (6'4") and have been more than pleased with the size. It fits in my pocket perfectly; I can use one hand to do everything; I don't have any trouble with the display at all.
However, I've noticed this general trend towards bigger phones as the future. In my mind, I always thought the larger the phone, the more the hassle. Phablets look utterly ridiculous. In your opinion, what are the benefits to a larger phone? Do you game? Is text larger/easier to read? I am genuinely interested.
As another note: I have my iPhone in a case. It's not an Otter Box or anything, but when I take it out of the case occasionally it feels ridiculously lightweight and small. After a few minutes/hours, the feeling normalizes and then suddenly the case, which was perfectly fine just a few hours ago, feels quite cumbersome. Could this be a factor in your perception?
