You are mixing up fine and same.if you really think that iphone 4, omnia and galaxy ace feel the same way than lets not even discuss it as your definition of fine it seems is different then mine.
Do I care the iphone 4 feels heavier ? no That it has glass instead of plastic back? Yes because that breaks easier.
As it should beEven i agree quality is in usage..anandtech just posted a hands on video on youtube and iPhone 5 is blazing fast..
