And that proves only one thing. People want bigger screen phones, and Apple is really dumb not making one! Yes, they are selling a lot of iPhones but maybe, just maybe, if they had a 5 inch phone they could sell double, or triple what they are selling now! I know I would buy one.
Don't worry, you are not required to understand Amazon's business plan. After all, if you would understand how their business works maybe you would be in the place of Jeff Bezos, a billionaire, instead of wasting your time on an obscure forum, right?
I think the Pattern Unlocking from Android and Windows phones is the best method for security on the phone. I don't think is better than a 20 character random password but much better than a 4 number pin or this fingerprint gimmick!
