Samsung is plastic
iPhone is aluminium
Care to compare two different materials??
Idiotic!![
He's not comparing two blocks of materials, he is comparing two phones.
When you buy a car, do you care about the exact mix of steel used in its engine? No, you care about design, about features, about performance...
When you take a plane, to you care about the particular brand of aluminum used? No, all you care about is that the wings will stay attached to the plane and will not bend...
When you buy a toilet seat, do you care about the precise brand of ceramic used or about what kind of steel was used to reinforce it? Nope. Unless you're an extremely obsessive individual, you just care that it won't crumble under you when you sit on it...
That's the same with a phone. You buy a phone based on its design, performance, application ecosystem, operating system... You don't care about the material. Picking the right material for the normal use of a phone is the burden of the manufacturer, not of the customer.
What the customer might care about is knowing if phone A is more resilient than phone B. How this resilience is achieved, whether it's through choice of material or layering of several materials or structure is really of no concern to the customer...
The problem is that you're looking at the whole problem with fanboy glasses. The issue is not too give a good mark for efforts to your favorite brand, whether it's Apple or Samsung. Only shareholder, employees or insane people care about that. The customer just doesn't give a damn about efforts, he just wants results. The issue is just to determine if a phone is fit for normal use or not.
