I love my iPhone, I don't know if I could switch to another brand now.
I totally agree.  I have had an iPhone since it was released in June 2007.  I loved the first-generation so much when it first came out.
My girls still have a 5, but I recently was gifted an 8 for my birthday.  It's so much bigger than my 5 but I love it.
It's hard to believe there have been eleven generations of iPhone models.  I still have a 6s but plan to upgrade to the X soon.  I love the 6s though and I've heard good things about the 8.
I think the girls will get new ones for Christmas, not sure which one yet - but they are honestly so pricey!!
They really are expensive.  Kids are pretty rough on their phones too. Not sure how your girls are, but the kids in my family aren't very careful with them:)
Well, they've both managed not to break the 5s and I think they've had them for about 3 years now, so not too bad!  But I'd thought of buying them Samsungs.
Samsung owners like their phones too, so that's not a bad idea.  It's hard to believe that my first cell phone could not shoot video, take photos, play music, send email, browse the web...etc.  It really amazes me how far phones have come.
