i am not a big screen person. coming from BlackBerry to the S3 was a major jump for me that i initially didn't like.
i've had the S3, S4, S5, S6 edge, and just got the S7 edge last week. i am still a bit on the fence about the size, but the battery life is so good, i don't want to give it up. i like the edge variant and i actually use the edge screen apps a significant amount, so the regular S7 was not really going to be an option for me.
i have another week to decide, but i think i'm going to keep it and try to get used to the size.
