While I used to be a computer hardware guy by degree and essentially haven't practiced this century I do have a very good phd level software engineered who work for me and we do collaborative development with a world reknown lab at Purdue. I once voiced about changing over to windows based OS from Linux on one of our instruments and the Purdue group looked at me like I had 3 heads and said why move from a stable platform to an unstable MS platform? My phd bought a motorola zoom and using android customizes and makes his own apps effortlessly. If he had design criteria and was tasked with it, i have no doubt he could design a stable EFIS system and not be hindered by Apples development guidelines. Both the Android and Linux platforms allow for easily implemented upgrades and customization and can be supported by independent "shareware" type development groups globally. For the masses who don't know how to type a URL in directly but rather always utilize google for their portal onto the web, MS and Apple are perfect.
For anyone who can think, there are better options. Rich Parker Greenfield NH Kr2s Unfortunately most of my PIC time over the past 10 years had been "Passenger In Coach"
