Ever since I bought my latest laptop it has been my primary machine, but after a while I started to miss the desktop configuration. Ergonomically it’s just so much better to have some distance between your screen and keyboard, unless you like having those extra curves in your posture.
So I bought a basic but fine secondhand USB keyboard for €3,- and used some random object from a giveaway corner as a support for my laptop. This way I’m basically recreating a (tower-free) desktop setup, using a laptop. I can still easily disconnect the input hardware and take it with me, so I consider it a “best of both worlds”.
