I miss 5 row horizontal sliders. The Sprint Samsung Galaxy S was the best selling variety despite Sprint being the 3rd largest carrier. People still want good keyboard phones.
Unfortunately, manufacturers either made keyboard phones with mid range specs, or downgraded the keyboards in both things like quality or to 4 rows. Then used the excuse to claim people didn't want keyboard phones.
Just like when manufacturers killed the stylus assuring that nobody wants them, yet the Note ended up one of the best selling phones despite even the premium prices. And it is shocking no manufacturer tried to compete with the Note, and no I don't mean those low end stylus phones that don't have pressure sensors in the display.
