Waveshare 7 inch 1080 x 1920, usb powered screen for the Raspberry Pi and portable operations?

It finally came in. The small HD screen I hope will become part of my standard kit. It's slightly larger than my phone and actually lighter, not including the cables. So far testing is going well, but until it's been stuffed in a pack and used in the field a few times I won't call it perfect just yet.
