Strengths Innovative – The Galaxy Tab has an innovative touch screen that is patented and unmatched by any other tablet today. It also has thousands of applications available for free under the Android OS market. Brand awareness – Samsung is well known for its white goods, mobile phones, etc.
along great technological innovations that they embed in their LCD TV’s. Whereas, for its competitor,i. e. , the Apple iPad is also a very well known brand but has a lower brand awareness than Samsung. Samsung has a higher brand awareness due to its wide range of products and diverse segments that it targets. Price – At Rs. 25000, the Galaxy Tab would be sold at a reasonable price for its value. It outperforms any other tablet in the market and the convenience of having multiple features combined into one-device increases its overall value. The Galaxy Tab would provide high end features at 33% lower price than its competitor the Apple iPad.
iPad – Rs. 37,500 Convenience of Carrying – The Galaxy Tab is very handy with its 7” screen and sleek design, comparing this to the Apple iPad it has a 10”screen and is 20% more in weight and 25% more in thickness. Weaknesses Image – The Apple brand is not targeted towards business people, which most smart phones have targeted. Does not have a reputation as being compatible with the corporate world. User Interface – Touch screen interfaces suffer from the problem of “gorilla arm,” in which long-term use of a flat, solid surface for input becomes uncomfortable.
Low market share in PC market– Though Samsung enjoys high brand awareness and market share in most of its products, it hasn’t been able to penetrate in to the PC market inspite of the notebooks(laptops) that they offer. Opportunities Increasing demand and expansion to a new target segment – Samsung will continue to target the business productivity market who wants an all in one computing solution. But as technology advances and tablets get cheaper companies also have a great opportunity to target people who want entertainment. Samsung will attract these consumers and get laptop users to shift to tablets.
Upgradeable – Since software on the Galaxy Tab can be updated, it allows new exciting features to be brought in which take advantage of the touch screen ability. 8.
