I started off with a flip phone - the AT&T Z331. Couldn't do much, but I got pretty good at SMS on the 10-key pad. 2 years later I got a nice upgrade to the iPhone 5 - and that was when that was the top of the line iPhone. I might upgrade it this year, since the battery is starting to bulge. I'm eyeballing the 7 and the 8 right now. Not the X, because the lack of a home button is sure to bug me.
