Mayday is truly a new level of customer service, and makes the phone a great choice for those who might struggle with new technology -- like the remaining population without a smartphone.
That's definitely an interesting addition. In the past, I've bought Nooks rather than Kindles as gifts for elderly relatives, because of the ability to just take it to the nearest brick-and-mortar B&N in case of trouble (or even just to buy books). Mayday isn't quite as good as that, but a clear step up from what's typically available for smartphone tech support.
If that's the target market - wouldn't a lower price point make more sense?
One big question - how much does mayday cost for amazon ?
People who don't yet have a smartphone have many reasons besides cost. Older people who are reluctant to move from a true phone to a multimodal pocket computer may be very happy with paying for one that has instant customer support.
