Contra
Para uma máquina centrada na produtividade, o Latitude 5490 certamente atende a maioria dos requisitos. Ele apresenta um forte desempenho de aplicativos, uma carcaça robusta e bem construída, ampla seleção de portas, excelentes dispositivos de entrada e bateria de duração excepcionalmente longa. Também é bastante silencioso e discreto durante o uso típico, por isso é adequado para um ambiente de escritório. As vantagens que esta configuração de $1.788 traz sobre o dispositivos que avaliamos em março são: o seu muito mais rápido, desempenho de múltiplos núcleos e single-core marginalmente mais rápido, um SSD NVMe de melhor desempenho, mais recursos de segurança, um teclado retroiluminado e uma tela táctil. Tudo isso é bem-vindo (apesar do custo - que discutiremos em um momento), exceto pela tela táctil, que torna a tela ruim ainda pior, convertendo-a de um painel antirreflexo escuro para um painel sombrio, escuro, e altamente refletivo que às vezes é quase inutilizável. Já dissemos isso antes, mas o 5490 precisa desesperadamente de uma tela muito mais brilhante com um acabamento antirreflexo.
Nenhuma máquina é perfeita e, pelo menos em termos de desempenho e duração da bateria, o Latitude 5490 tem poucos concorrentes em sua classe. Se apenas a tela fosse melhor, poderíamos recomendá-lo de todo coração.
Além desta queixa principal, existem alguns outros problemas: a máquina é bastante pesada, falta Thunderbolt 3 e o consumo de energia e as temperaturas da superfície não são ideais. Alguns concorrentes—como o HP EliteBook 840 G4 e Lenovo ThinkPad T480—lidam com esses itens de forma mais efetiva. O próprio Latitude 7490 e 7390 da Dell, também são excelentes alternativas (embora mais caras) para este dispositivo, que possuem muito poucas falhas. No entanto, nenhuma máquina é perfeita e, pelo menos em termos de desempenho e duração da bateria, o Latitude 5490 tem poucos concorrentes em sua classe. Se apenas a tela fosse melhor, poderíamos recomendá-lo de todo coração.
