Rumor has it that Fedex has already made a large IPad purchase a few months ago. I know this from the Jepp side not the Fedex side. Same source told me Fedex was switching to Jepps...first dispatch, then simulators, then FMS, and then EFB hardware. From my observations it has happened in that order...which makes the IPad part highly likely also. Also flew with a few Flex guys who "secretly" told the same story several months ago.
