It’s a good point. However, the convenience of having a laptop may make it worth it to the user even if it’s not used as a laptop as much.Surely you’d get better value buying a Mini or a Studio?
I’m one such cases
Years ago, though less than 5, I used to carry my personal laptop around more. Now, I rarely do but at least a few times a year may need to such as when visiting family abroad and instead of carrying both a work and personal laptop I just carry the personal one and do work on the personal one.
In fact, my office issues only laptops and no desktops to all of us even though 95% of the time is docked. The other 5% of the time, it is moved here and there. The flexibility is worth it.
