It is very important to know that although it may seem that Samsung is 'developing' very fast, it has yet not done any kind of major innovation, most of its strategies are on the marketing segment, while Sony always surprises us with their style, creativity and designs.
Moreover, reporting losses is not unusual for Sony, in fact I believe this is their case most of the time because they make long-term investments; for examepl, currently the Cell processor and the Blu-ray, their investments in these two items are yet to pay off. |
