Having two of them on opposite side as the new Pixel does is certainly convenient, even more so because the port is flexible: you can just plug your stuff in whichever port is more convenient in terms of distance/position. Have a power plug to the left? Plug it to the left port. To the right? Plug to the right port. That is by far the main reason why I'm bothered by Apple's MB and its single Type C, while having a single one may be sufficient having one on each side is significantly more convenient.
