People pay 5$ for Starbucks Latte when they can make coffee (maybe better even) at home in 5 mins. It is laziness, convenience etc. Or simply, one less thing to think about (assuming m3o's service works well etc), which alone is a good enough reason to pay for it.

Any external service is not "one less thing to think about" but "one more thing to think about" (security, refilling account, check alive status...).
