Smartphones with physical QWERTY keyboards aren't unheard of but aren't exactly many. Even fewer are those with keyboards that slide out. And even rarer are those that slide out horizontally in a landscape orientation. That kind of form factor hasn't been seen since perhaps the Motorola DROID 4, but soon that might appear again, coincidentally in another Motorola smartphone. No, Motorola isn't making a new QWERTY slider. But thanks to its Moto Mods, someone else can make that happen. If, however, the price, or rather the funding, is right.
