That's $20,000,000 (per 10 million units sold) that someone would have to pay for. They're not going to increase the phone by $2 to cover that cost, so they would have to pay for it. And for what reason? Their 2gb phone from last year is still beating the new 8gb(6gb?) phones from this year. To be honest, I'm surprised they upped it at all.
They upped it. Reminds me of this funny thing my Pastor said once when talking about charitable giving. He was making the point that he should and was going to lead by example. About giving he said, "I upped mine so....up yours!"
In my opinion, is simply gonna do what they wanna do -- we all know it and we still love their products. Would it be cool for them to release a new phone at last year's prices with 16gb Ram and 1tb storage in "Quark Blue"? Hellz yeah! But they didn't and won't unless/until that configuration solves a problem.
