Just store RetroPie or Kodi on your MMC and you have the perfect device to take with you to hotels and friends' homes, especially on a holiday like this where you are likely to need entertainment.
The connector HDMI sits on a carrier board that houses the Compute Module and adds a USB-C port for power and two USB 2.0s, one of which might be ideal for adding an IR sensor to give commands via a remote control. There is a microSD card slot, a switch to enable the CM4's USB device mode, and a mysterious user button, the purpose of which has not been specified.

On both, the Raspberry Pi Compute Module 4 is connected in the same way, but there are slight differences inherent in the heat sinks used for passive cooling. Finally, GPIO access is left available for further hacking activities.
