I'm with Piltdown Man on this one...
Honeywell FMS on A320 is a joke, takes 10-15 seconds to calculate a simple thing like where the aircraft will reach FCU with V/S -1000 ft/min. Also, the infamous PAGE UPDATE IN PROCESS is there just to piss you off.
Not to mention the intentionally hidden and very onerous ways of entering airways. Especially when you have an airway, followed by direct, followed by airway, etc. - as is the case with modern airspace.
When they manage to bring the current technology to a level that is not a pain to operate on a daily basis, I'd be glad to see what they can do with mind controlled systems.
