I'd prefer a keyboard than a folding screen to be honest. I mean, I loved the RAZR when I had it but part of the appeal was that it was a smaller phone, not a bigger one. These days I have an iPhone SE because the 6 Plus was just too big. I want an affordable phone that I can carry in the pocket, not some behemoth I have to drag behind me in a wheelbarrow.
It's great that they've brought back the RAZR format, but more homework is needed I think.
