Perhaps my consumer lifestyle strangely aligns Amazon's incentives with mine, but I'm actually really happy how they solved the problem of me buying more stuff from them. It seems that they observed
very common patterns people already use poorly and streamlined them.
Case in point, almost everyone I know takes pictures of books and items they want to buy or investigate further later. Currently this 1) clutters my Photos app with this overloaded behavior and 2) additionally requires me to then manually re-enter the information/remember to look it up. Just having Amazon scan and put it on some list for me is killer in my opinion.
Additionally, I've wanted something like X-Ray for so long and it seems so obvious. Shazam style movie/tv show detection and bringing up IMDB and other useful info on my phone is great. Having Airplay style functionality built into Samsung TVs and play stations is also great (hopefully we will move to a standard protocol to stream video content to TVs in the near future, but this is a positive step in my opinion from just Apple TV in Apple land and just Amazon TV in Amazon land).
I think Mayday may just be the feature though. People like me will have no use for it, but its definitely the case that most people don't really know what they're doing at all with their devices. The threshold for "user friendly" is so laughable right now. iOS AND Android really are quite complex for any non-standard task ("What does it mean I've run out of iCloud space??"). And this is not easily implementable I think -- it will take serious investment to copy this feature on other platforms, you can't get away with a half-baked software solution.
