I can confirm. I work at a school with a massive fleet of Macs. The kids generally kill their devices with water by keeping their water bottle in the same bag as their MacBook. Doesn’t matter how often I tell them not to, they insist on doing this.
There are backpacks with bottle holders on the outside, but in my experience, those aren’t very good at holding a bottle.
Not bringing a bottle probably is the best option, but that may not be a good option in very hot climates.
How would you avoid water damage due to the scenario? Or do you consider it normal and unavoidable?
And some backpacks actually have working bottle holders on the outside ...
