Ask HN: Why don't buildings have dry warm up rooms for your laptop in winter?

In winter, a laptop can get cold enough during a long walk or commute that it picks up moisture as soon as you enter a warm building. Powering on a damp laptop can cause damage, so a simple solution came to mind.

Public buildings like malls or libraries could offer a small dry warm up room where people take their cold laptops for ten to twenty minutes. The room would be warm with low humidity so the device can reach indoor temperature without collecting moisture.

Would you use these dry warm up rooms to protect your laptop from water damage during winter?
