People say want smaller phones that fit in their pockets -- myself included. But are they willing to accept the much lower battery life, the smaller text on the screen, and the reduced real estate on the screen?
My solution is simple, I carry two phones a tiny dumb/feature phone for just phone calls and a smartphone for internet access.
No one can phone me on my smartphone as it uses a data-only SIM so it's difficult for Google and others to make sense of the data they steal from me (even then they only receive data garbage for reasons I won't bother to mention here).
It's hardly less convenient as the dumb phone is small enough to fit in my shirt pocket whereas the smartphone is in a trousers pocket.
The smaller iPhones didn't sell well.
