Did not know about this, thanks for pointing it out. It is not precisely what I had in mind, but appealing none the less.

The phone I had in mind is akin to Motorola's RAZR Ultra. As opposed to opening like a book the way Samsung's latest does, unfolding the "top" half provides a smaller-than-average smartphone screen, leaving room for a Blackberry-style keyboard below.

I'm in that niche market where I do not need a large screen on my phone since I am mostly reading text as opposed to watching media. It's not likely I'll ever get precisely what I want due to practicality of both manufacturing and what the general market demands are. I've come to terms with it, but if someone ever drops such a device, I will get in line for it.
