I get why these types of devices are appealing from an "oooh new shiny" perspective but let's be honest: the smartphone design is essentially perfected. Software keyboards are far better than physical ones at that size due to the adaptive keyboard touch target re-sizing that goes on behind the scenes. Just use your existing phone and delete all the distracting stuff, it'll be far more reliable than some small-batch manufacturing run of something like this.
