No sense in waiting to get the phone to prove him "wrong". The phone is / will be amazing and the biggest reason I personally bought it was for its size. The guy who wrote the article doesn't like things that are big.......just the same way some people would prefer to drive a Civic over a lifted F350 Diesel. Big deal? The guy is entitled to his opinion as much as you are entitled to your right to buy and enjoy the best smartphone currently out.
I will give him 2 thumbs up on the comment about Android Phones having 7 different flagships in the same year......that part needed to be said. Each time I walk into an AT&T or Verizon store, they have a different lineup of Android phones....but the iPhone is sitting there...in the same place it has for months.....and still outselling all the rest.
Be secure with your purchase - and use it because YOU want to use it, not to use it to prove someone else wrong. That's just......silly.
