I doubt that Boeing or any airline is going to have the slightest urge to pay huge $$$$ to replace flight computers on commercial airliners everytime a new software upgrade is proposed. to do so would be stupid. you must realize that *real world* encompasses a hell of alot more than mainframe and PC programming. if you're doing that kind of work then sure, buy the latest hardware. now wait three years, increase the program's functionality 50% and only be able to add a limited amount of memory to the system and no processor upgrades. welcome to a whole new real world.
