You described the BlackBerry Priv.
:o a slide-out keyboard in vertical orientation in 2015, I wish I had that phone
I used my Priv for five years, best phone I've ever had, barring some battery & heat issues. Showing people a normal-looking phone and then sliding out the keyboard was a fun party trick. If there were any modern phone like it I would buy it in a heartbeat.
