BIG discussion going on right now at the AFFSA level about EFBs (Electronic Flight Bags). Nothing approved on a force-wide level yet, but different folks are looking at different options. The big issues about electronics and approval for flight under instrument conditions, etc. have all been raised in the above posts. Same thing we just got from the bubbas in OK City.
Bottom Line: NGA DVD in a fly-away laptop is money. Plan on probably sticking with paper for foreseeable future. NGA has some great tools that you can use to collect all your IAPs, SIDs, etc. for a trip and print them.
Cheers!
