well, when it comes to replacing wallet, we in India need a whole ecosystem of paying through NFC's which i don't see happening for atleast a decade.
i liked apple watch, but price is too high plus the dependency of having iphone just makes it a no-go for many android users. i would love to own the motorola smartwatch if it's priced reasonably within 5,000-7000 ( i know it is priced 250 $ abroad)
