We also have relatively small smartphones. I wonder from time to time
whether the new big iPhone or the android equivalents would eliminate
one device, but I am inclined to think you need a pocketable phone and
a minimum of 7 inch screen for most "tablet" applications, i.e. two
separate devices. It is handy to be able to check email on a small
phone, but easier to reply using a tablet or laptop unless it is just
yes or no.

My son has just exchanged the new larger iPhone for the new smaller one.
He must have had a reason.
