JetBlue also uses OPS. We run it on issued laptops that stay with the pilot, though, not the airplane. So far the laptop is not directly linked to the airplane. It may happen someday, but that's a ways down the road.
We're also specifically authorized to use the laptops in flight (above 10000 ft, of course, or in an emergency), since they're loaded with company manuals, aircraft manuals, MEL, etc. We don't have paper copies of any of that. Only the checklist and QRH are on paper. And most company communications are through email. The Jepp charts are paper, but supposedly something is in the works to change that, too. It'll be nice to do away with revisions entirely.
It's not quite a true electronic flight bag, but it's a huge step in the right direction. For now, I'll settle for having all of our gates wired with wireless net access. It's already available in some places, but not everywhere. It's a neat way to get a quick check of rapidly changing weather, for instance. Or just check messages on airliners.net.
