Sleeping on my back is soooo relaxing… when I can fall asleep. For some reason I have the hardest time falling asleep on my back, but when it does happen it’s bliss.
This is not distro specific advice but: when starting out you can use a virtual machine like VMware to test drive Linux without having to repartition your drive. VMware is free for individual non commercial use.
Another approach is rather than worry about whether the robot or IoT device is respecting your privacy, set up your network to be segmented with VLANs so that the IoT devices can only reach the internet and nothing else on your network. Then just provide fake info for setting up accounts with the IoT devices.
