Folding phones would make sense if I could fold/unfold them twice and get 4x the space with same aspect ratio, transforming a phone into a tablet. Otherwise it's just a gimmick and waste of money. I know some people might praise these for multi-tasking but I can't see myself doing two things at the same time on a freakin' phone (maybe except reading a book in foreign language and using a dictionary at the same time which is what I do often) and I would rather grab a laptop for that.
