This doesn’t surprise me in the least. In fact, voice communication is now definitely a minority activity and calls brings into question the continued use of the word smartphone.
Our phones are now mini-computers and deserve a more all-encompassing description. O2 suggest we use “Best Buds”. If this is all they can come up with, then beam me up Scotty.
As usual, a name will come from common usage and it won’t be something we can just dream up. It’s probably out there already. Talk to a German, for instance, and he will show you his Handy. In many ways, this English-sounding but totally alien description is actually very appropriate. That’s what our smartphones have become: they are Handies. Time to bring the Deutschlisch word back into English.
