ROFL..
As someone who works for a none HK outfit currently going through the transition to a bespoke in house iPad solution can I say
: Be careful what you wish for..
Make sure your management buy a product that is time served and has been Beta tested by some other poor s**ds in another airline and works out of the box for you guys from day one.
Do not, on any account be railroaded into struggling along with some half ased/cheap app that management want you to Beta test, because trust me if you do that you will get management messages along the lines of ..."oh, we didn't know you wanted to be able to dim the screen at night"," oh you want it to have a > 6 hour battery life?" ( no hard wired power supply for us)...."oh, so you don't want the all important charting app to disppear off into the ether, lock up, and try to find a network/update/go into sleep mode when you are crossing the FAF whilst IMC?"...and ultimately: "Despite all the above we're sure you can work though it and the paper will be going in two weeks time" (actually ours backed down and we're still using paper charts)
