I’ve had the experience in dealing with computer hardware for 15 years now.In these years, I’ve used, sold, recommended and experienced the life cycles of HP, Dell, IBM (Lenovo) and Apple products. One difference I’ve noticed with Apple is that their products are NOT designed just for competitive sales, they’re made to be useable. They decide the pricing after all the required quality and design parameters have been met. The other companies make products to compete in prices and features, not usability.
Here’s a Forbes article that aptly describes why Apple beats Dell, and probably other vendors like Lenovo.
In technology, its not just about prices and features, its about design, usability and a lot more. Unless brands get it right and innovate, the chances that they will remain forever is low.
