I think we'll see the turb, wx, moving map, flt plan and some other cool things. Jepp has it but DAL isn't even begun the testing phase yet. Actually we're doing something nobody else is doing... introducing 2 different devices at the same time and doing dual certificate testing. I think the add-on's layer on too much complexity to the initial testing. In actuality, there are several airlines very excited to move to the Microsoft system and Windows 8. For a corporation, it's much easier to support one OS than several different (just look at how amicable DAL is to MAC users--I can't even get Safari to load DL NET). Once the test is over and all the fleets move to the Surface, I suspect the add-on's will be turned on (maybe not all at once though).
