This. Additionally desktop parts last longer and can be upgraded individually. They also have good resale value, offsetting the cost of upgrades (especially true for GPUs).
True even for the mini form factor (the 1L desktop that uses laptop component). As you do not have to stay close to it, you have a great experience out of the box. I could use a chromebook for what I still use the laptop for (browsing and ssh from the sofa)
