It makes it impossible to confirm the laptop is truly off, because opening it to check turns it on. This was especially annoying during my "boarding a plane" ritual where I check everything is right before settling in.
Fridges have this problem too, but if you’re taking one of them on a plane it’s your own fault.
It will try to start up the applications I least care about; meanwhile ignoring the actual context I desire, which just slows me down more.
Something like Outlook or OneNote will restore its state reasonably well, as will Safari/Chrome/Edge/Firefox. Others, like Activity Monitor, Enpass, and iTerm2, decide to "helpfully" open a window for me even though the previous state was "running with no windows open" (which is perfectly valid for many applications).
This is on a Mac though, so (for me anyway) this is something that just works without any fuss.
