Upside Down Devices

The iPad and iPhone, and most smartphones, can be placed upside down

This would seem to be a simple statement, but I’ve seen a number of reviews of desk stands, trays, and various products which hold those touchscreen devices complaining that the device in question provides no facility for the cable to stick out of the bottom, or that it requires a very specifc cable, and won’t accomodate some aftermarket cables. Did no-one notice that these devices work upside down, and the cable could stick out the top just fine?
