Like most places, there is much of our information we deal with that is web based. Scheduling, weather, maintenance along with security info are just some of the items. Security info and company reports are best left off public hotel or internet cafes for security reasons.
One example, the company doesn't issue or permit the pilots to print our bids in operations. A 4 day trip with one's own PC makes dealing with that easier when they're issued.
Email with the company in weather events is another gain for the company. When the system goes down, the phones tend to follow.
If anything, I'd just move it up on the priority list when choosing layover hotels. It can take the place of "available shopping", which I'd move way down the list.
Hope this helped
