Re: Margin is the issue here...
>>Apple are addicted to profit margin.<<
Where do you get that simplistic analysis from. It is wrong. Companies must make a profit to stay in business. Apple are addicted to that.
Other companies try to compete with Apple by undercutting on price. That does not mean the make their devices for less - equivalent devices cost more or less the same.
How do they do it? They cut the quality - drastically. They use free open source from Google and Android - software that has been developed freely by many open-source developers.
Secondly, a large, diverse company like Samsung can subsidise their tablet/phone market from other sources. Once they succeed in putting Apple out of business (not that I'm saying they will), they put up the prices again.
