The hard reality is that there is no PAYING market for such a device, because when it comes to the point-of-sale, most people still choose the normal-size device with better screen/battery/camera. This is equivalent to something I called the "QWERTY paradox" more than a decade ago: Back when the Smartphone market exploded, people disliked typing on a touchscreen and repeatedly stated that they want a device with a ph…
> But whenever someone answered the call and built a Smartphone with QWERTY keyboard, the product failed commercially, simply because also to people claiming they want such a phone, at the point of sale they were less attractive than their slimmer, lighter, all-screen counterparts. I bought Motorola Droid 4 when it came out. I was so desperate to have a new phone with physical QWERTY, that I bought it blindly, even t…
This is an odd conclusion considering that the Droid 4 was already the FOURTH iteration of a QWERTY device from that ONE brand on that ONE carrier, each iteration selling less than the one before as each faced more competition.
If you're interested, the actual reason for the end of the Droid QWERTY series was that the entire "Droid" brand was a Verizon-exclusive product-line with a big focus in sales and big budget in Marketing, just to compete with the iPhone (which was not available on Verizon until 2011).
For a vendor to win a slot in that lineup meant that Verizon Sales and Marketing put all weight behind selling that device, no matter what device it is. This made the Droid 1 and 2 a huge success, not because of the product but because of the sales channel.
But in year 3 (2011), the iPhone launched on Verizon, which put a huge dent in both sales-focus and budget of Verizon's "Droid" product-line.
Later that year, Droid 3 launched but was selling significantly less than its predecessors.
In that year, Verizon instead sold 6.5m iPhones (up from ZERO iPhones the year before).
So Motorola had to cut their losses on the already ongoing development of the Droid 4, the device was redesigned for a much lower total sales-expectation and then launched in 2012.
But the sales turned out even lower than expected: By Q4 2012 Verizon sold 14m Smartphones, with 10m (!) of them being iPhones.
The most successful Motorola device of that year was the Droid RAZR MAXX HD, a non-QWERTY flagship.
It was clear: That QWERTY keyboard didn't drive sales.
