Haha I thought that device was long forgotten!

Actually the HTC S740 was one of the inspirations for my keyboard layout.


As I said before, this is what I think is the pinnacle of a hardware keyboard for a ~5in device.
Its function over form at its max.
Keeping the important keys, and hiding the rest as Secondary ones (Activated via Ctrl), and do away with the rest. A small light indicates when Ctrl or the Shift (Caps Lock) is active. The circle at the right is actually a Trackball (think Blackberry) which helps control the cursor with awesome tactile feedback.

All in all, keep everything big, bland, easy to see and type away!

PS That Jolla photo is actually just a render.
