I will mention, based off personal experience, if you aren't very geeky or technologically savvy you might actually like the iPhone. I had one for several years and it is very intuitive to use. Also, the phone itself is very well made. Had zero issues with mine. Ever.

I like my S5 better than the iPhone because I'm getting better at figuring stuff like that out now. But it does do stupid things every now and then and you have to restart it or sometimes even pull the battery to unlock the darn thing. Not often. Maybe once a month or two. But my iPhone never did anything like that. It just worked.
