I was wrong on the tablets, I was meaning an ideal tablet for watching TV/films which is mostly 16:9 or 18:9.

Tablets typically are 4:3, which would result in a phone being 3:2 which would be 25% shorter on 18:9 phones, and 15% shorter on 16:9 phones, which is a reasonable departure from the norm, and ultimately means neither the phone nor the tablet are well set up for watching films/TV.
