i strongly suggest everyone not sign up with telco to get iphone7,
because 2 years contract is bloody long long long period..

we can't just evaluate the value of the plan based current package in the market,
because with the price war & competition started by Umobile, Webe & follow by other telco.
data price will be getting cheaper & cheaper & cheaper in coming 2 years.
The value of the 2 years contract package that we tied up definitely will become worth 50% only from the monthly fee we paid after 1 year.

better just purchase upfront from Machines, Switch, MacStudio since price difference not so huge,
and we have the freedom to changing telco package in future..
moreover if next year really come out iphone8 (instead of iphone7s) with huge improvement then we still can upgrade since iphone resell value not too bad.

dont get con by the telco... now a day telco they so concern on customer retention,
that's y all 2 years contract..
i'm sure they "pakat" together already, it's impossible so coincident all 2 years contract..
