Pro
Contra
O Dell Latitude 5490 possui muitos pontos positivos, especialmente para empresas e seus empregados: Durante o uso em escritório, é muito eficiente e, graças à operação sem ventilador, muito silencioso. Os dispositivos de entrada também são de alta qualidade, mas a maior vantagem deste portátil é sua incrível duração da bateria, permitindo um dia de uso com tarefas menos exigentes. A coleção completa e opcional de recursos de segurança pode ser um argumento de compra igualmente bom.
É por isso que nos chateia tanto em ver que a Dell não tenha resolvido o maior ponto de crítica encontrado no predecessor, a tela escura. Embora oferece maior contraste e melhores níveis de preto que antes, ainda não é muito brilhante. E para piorar, sofre de terríveis tempos de reação e descoloração. O ruído da ventoinha sob uso intenso também poderia ser melhorado.
O 5490 está claramente destinado para empresas e seus empregados. No entanto, deve-se selecionar com cuidado as inúmeras configurações em oferta para receber o conjunto de recursos desejado. Para clientes menos preocupados com a segurança, certamente existem alternativas mais leves, menores, e mais silenciosas sob uso intenso, que normalmente também podem ser mais acessíveis. Aqueles interessados receberão um portátil empresarial seguro, poderoso e duradouro com uma tela, infelizmente, muito escura.
O 5490 é um pouco mais fino que o seu predecessor, mas a atualização Kaby-Lake raramente resulta em um desempenho melhorado no uso real. Em muitos aplicativos, o 5480 é, de fato, um pouco mais veloz. Talvez poderia valr a pena dar uma olhada no predecessor, no entanto, devemos mencionar que o 5480 é ainda mais barulhento sob uso intenso.
