Am I the only who feels this way about the iPhone 6?
When my iPhone 6 arrived this morning, as I was holding onto it, I realized I made a mistake and never should have ordered this phone. I should have just upgraded to the iPhone 5S. Granted, I was vehemently against Apple increasing the iPhone 5 to 4". When the iPhone 5 came out, the size was outrageous! I love my iPhone 4S and wish Apple would have stayed with 3.5". The iPhone 6 is too hard to use. I have to use it with two hands. How am I supposed to multi-task and use my iPhone 6 one-handed?! I'm seriously thinking of returning my phone or selling it. This decision to increase the size to keep up with Android saddens my heart.

Not sure if OP is trolling...
It's just the first day, but I already I don't like it. I can't comfortably grip it with one hand. I have to use two hands. It's just too big. .
i hope every single member of the forum starts a thread to let us know what they think of their phones.

If it's already too big to one-hand, then you might as well get the 6 Plus!
In all seriousness though, I've been hearing this from a lot of womenmy wife included. She refuses to upgrade to a bigger phone. I just wrote a thread about it actually. I'm hoping that they at least keep around a "C" model that is 4" so people like my wife can stay happy. For instance, an iPhone 6C in two years. By then her iPhone 5 won't support iOS X.
This forum can be really hostile towards people who complain about anything related to Apple products.
On another note, I'm sorry you don't like the phone. Like others I would recommend buying a 5S or checking out a smaller Android or Windows device. You're going to have trouble finding something close to 3.5" or 4", although the Sony Xperia Z3 has a very small form factor with a larger screen.
I would keep using the iPhone for a couple of days and see if you can adjust. I've found Reachability to be really useful for using the phone with one hand.
Sounds like my wife talking
