Since aviation became an industry, adding more "things" is always circumspect. If you think about it, that makes sense since every new feature, by virtue of being "new", still has to go through a gauntlet of testing, retesting and independent verification (plus Aviation Authority approval from several different countries). There may have been previous attempts that were possibly abandoned until now when technology has finally caught up to the expected reliability. Well, we shall see. If the Boeing battery problems[1] are a hint, it will take actual major use to bring out any bugs. But I'm still hopeful.
