I don't know about that. I went to buy a iphone 6 and realized it would not fit in my jeans pocket very well. Decided to pass for now. Since getting an ipad I hardly use the phone for much more than email, camera and actual phone calls and the laptop is really gathering dust. I would much rather have a smaller phone and a tablet than an over sized phone.
It's interesting because I'm the exact opposite. I had an original ipad before I had a smartphone, used it all the time, but then saw an immediate drop in usage when I got the phone. Now as I've gotten more and more used to the phone over the years, my ipad has really started gathering dust.
