Tech manufacturers are struggling to make folding devices. So far the folding smartphones are not where they need to be. Lenovo has taken a different approach, by building a folding tablet first, and not a folding smartphone.
Whether this will be a hit remains to be seen. But as the Yanko Design piece shows, the chance of success with a folding tablet is much higher than a folding phone. If it is a hit, it could lead to smaller devices (i.e., phones) eventually getting that way too.
