A reader shares a report: Next week, Amazon will start delivering packages straight into Americans' homes, using a smart lock and camera device called Amazon Key. But will anyone bother paying for what seems like an invasive service? Most wouldn't. About 58 percent of people who have Amazon Prime definitely would not buy Amazon Key, according to a SurveyMonkey poll done on behalf of Recode. That's only slightly less than the 61 percent of all U.S. adults who wouldn't buy the product, suggesting it's broadly unattractive, regardless of whether people are Amazon customers. Among Prime subscribers, only 5 percent said they would definitely buy Amazon Key. Of all U.S. shoppers, even less -- 4 percent -- said they would. Nearly 60 percent of the respondents have Prime subscriptions.
