In the US, UAL is also going to ipads, and Delta is studying the issue. One of the big regional airline conglomerations is also using them.
So far, in the US, the places I have heard that use them for EFBs, issue one to each pilot. All their pubs, jepps, etc., etc. are on them. They have no paper in the cockpit.
The airline I fly for is getting a tablet that all our pubs will be on. We are also getting EFBs, but that status is unknown. I wish we would just get the ipad and use it for both, as all the above airlines are doing.
