Yeah, most of my computer use is with a properly adjusted desk setup with external monitors and while it doesn’t bother me to use a laptop to jot down some notes or for a short study session, if I try to do “real” work at all I quickly become uncomfortable. A cheap folding laptop stand (which elevates the laptop enough that the middle of its screen is eye level) and wireless KB+mouse dramatically improves comfort (and productivity) but the tradeoff is that you need a table or other sizable, stable flat surface.

The exception is if there happens to be a reclined-position chair (IKEA POÄNG or similar) around; this gives back support and reduces neck craning enough to make longer sessions more viable, but it’s far from a given that this kind of seating will be available.

If you have interesting enough work, nothing else matters. I have written big complex systems while car pooling on a laptop in the passenger seat.

The reason for this app is not productivity but for posture.
