I'll be honest. I was in college when the iPhone dropped. I think I was my freshman year. I saw a few people with them and I was like this thing will never catch on. I had a Blackberry 8830 and I thought it was so amazing. And I never thought touch keyboards would take off in such a big way.
Obviously I was mistaken and I've had multiple iPhones now. That said for all their advancement I still, once in a while, look at the BlackBerry Passport and consider buying one...just because it's a square :)
