SmarTone's really positionning itself as the Android vendor in HK
Ok, so after being the official vendor of the Hero in Hong Kong, the Android platoform's former flagship handset is now proposing to hand you HK$4280 if you bring them your Nexus One and sign a monthly contract of HK$398 for two years. That's HK$410 with the fee.
If you bring a phone to them, you sign a 18-month contract and would pay for HK$250 (238+12) a month. If you do the maths, say if we extend this contract to 24 months, you would pay $6000 (250*24) at the end of it. With the other plan, it's HK$9840 (410*24), minus the rebate it's HK$5560.
So the longer contract by six months, and the special plan for Nexus Ones, will save you some 440 over two years, or about HK$19 a month.
