Saying the screen size is bigger as a better feature than the iPhone is stupid and you should feel stupid.
"HEY GUISE I CAN MAKE PHONE CALLS WITH MY TABLET." *puts brick to face* "HEY HOW'S IT GOIN?"
The screen size on the iPhone is perfect. I can reach around the entire screen space without shifting my hand's position at all.
I can do that with my android too. I cannot stand having to get right up next to the screen of an iPhone to type etc, the screen is just way too small for me (and a really weird resolution). Please do not say that a smartphone is a tablet. I would take the S4/Nexus size screen any day over an iPhone's. You can see from the picture that the overall phone sizes are less different than the screen sizes.
And as far as comfort, I prefer to not hold a brick in my hand. Androids fit into your palm by curving out a little, and even place the power button on the right side where your thumb goes.
I try to not come off as an "elitist prick", I just want to help people invest in the best phone and give android a chance (as it is the underdog in the US). For many, an iPhone is the best choice due to how basic/common it is. But if you are posting here on the Blockland Forums, chances are that an Android is for you.
