You got a point there. Not all features on iPhone can be utilized, especially siri although sometimes its fun talking with siri hehehehe but isn't it always true on all phones? I mean every phone has its unique feature but you'll end up using more on its main feature (call & text messaging. well of course it's a phone

) The best thing with iPhone is it's faster, clear display and more responsive thats what you paid for its higher cost. If responsiveness is not an issue go for android (still user's preference)
PLan 5000 is surely not for middle class individual its for businessmen. THere is a plan 999 + 999/mo for iPhone on smart. 999 for your data plan and 999/mo for iPhone, 2 years lock-in period so you'll be paying less than 24,000.00 for the iPhone. That is cheaper than buying an iPhone today and its in installment.
It's a good thing you have this tip bro at least it can help someone in his/her decision making.
P.S. What's the best phone or what can you recommend for middle class?
