Pro
Contra
Embora não chegue perto do glamour dos seus irmãos XPS de 13 e 15 polegadas da própria Dell, o Latitude 7480 é de certa forma o equivalente empresarial daquelas máquinas mainstream bem recebidas. O portátil de 14-polegadas de bom visual é menor e muito mais leve que antes, mas a qualidade de construção continua sendo inquestionavelmente alta. O chassi é sólido com tolerâncias apertadas e possui um acabamento suave e amigável ao toque. A tela é brilhante com cores precisas e revestimento antirefletivo, portanto, os viajantes não terão que lidar com reflexos irritantes. O desempenho é de primeira categoria - embora os testes específicos da CPU fiquem um pouco para trás, o portátil se destaca quando se trata de benchmarks sintéticos - e a bateria dura todo o dia mesmo sem ser completamente carregada. Os dispositivos de entrada também são muito bons com o teclado em particular, recebendo o nosso assentimento como um dos melhores disponíveis no mercado atualmente.
O Latitude 7480 é um portátil empresarial sólido de alta qualidade. No entanto, o barulho de sua bobina poderia ser um fator decisivo para alguns.
Se houver uma pontos negativo flagrante, é o barulho da bobina, que é audível há pelo menos 3 metros de distância e parece estar presente independentemente do nível de uso (mas é claro, mais perceptível durante o modo inativo). Certamente esperamos que este barulho afete apenas o nosso modelo de teste, mas dado que observamos o mesmo tipo de barulho durante nossa análise do Latitude 5480 e 7280, não ficaríamos surpresos se este for um problema mais espalhado.
