Yeah, and Amazon's profit margins are notoriously and historically razor thin -- interestingly it's a matter of policy. Redirecting profits to other departments for maximizing revenue generation, which results in completely opaque expenditure/profit reports.

Mobile handsets may be the largest slice of the pie, but that's only because it's so easy to pad the margins.

Furthermore there is value to participating in other industries, even if only to break even. The expertise and business relationships are certainly contributing to Samsung's bottom line in ways other than revenue.
