Big monitor and standing desk -- those are the two things I miss when I travel/work. The monitor can be purchased locally usually and then sold/given away when leaving, but the desk is something I haven't solved yet.
For the last 15 years, almost all of my computer work, gaming, Netflix, etc. stuff is done standing. I find sitting unpleasant now (which makes 12 hour flights a literal pain sometimes). I'm almost never tired standing, even after an entire waking day on my feet.
