Mobile World Congress prompted HP to present a tablet from HP, called the Pro x2. AnandTech has the full details. As befitting a newly introduced tablet, HP included a USB-C port that supports both charging and display output. But what’s even more interesting, is the fact that HP is going to offer a USB-C dock (US$ 149) and a travel hub (US$ 49). As soon as details are available, we’ll update with more information.
