Contra
O Dell Latitude 7380 divide a diferença no tamanho da tela entre os carros-chefes existentes da série Latitude 7000, o 7280 e 7480—mas, em muitos aspectos, é menos um compromisso e mais uma evolução intra geracional. Arrancando uma página do livro do XPS 13, o 7380 coloca uma tela de 13,3 polegadas (e, em sua maior parte, todo o corpo) do existente 7280 de 12,5 polegadas—por isso, de muitas maneiras, o substitui. O melhor de tudo, realmente não há grandes pontos negativos para esta abordagem: a estabilidade da carcaça ainda é muito boa em geral e, embora a tampa da tela não possa igualar a rigidez da estrutura de alumínio do XPS 13, a construção de magnésio do Latitude não é nada frágil.
O Dell Latitude 7380 divide a diferença no tamanho da tela - mas de muitas maneiras, é menos um compromisso e mais uma evolução intra geracional. Começa com a base estabelecida pelo XPS 13 de nível consumidor, mas fornece todas as sensibilidades empresariais implicadas pela marca Latitude.
Também ficamos satisfeitos com o excelente desempenho do sistema do 7380 e as velocidades da CPU na maior parte consistentes sob carga; junto com as baixas temperaturas da superfície e o ruído do ventilador bastante discreto, os resultados são impressionantes para uma máquina desse tamanho. Ainda mais impressionantes foram nossos testes de bateria, onde conseguimos mais de dez horas de navegação na web com uma única carga. Além disso, a tela IPS de 1080p também está acima da média, embora exija uma calibração profissional para ter algum grau de precisão de cores.
Nossas únicas queixas são o ruído eletrônico/de bobina moderadamente perceptível, a imprecisão da tla no estado de fábrica e o alto preço acima mencionado de $2.178. Também é um pouco decepcionante que apenas a memória de um canal seja suportada, embora a capacidade total de 16 GB seja mais que suficiente para esta classe de portátil. Os concorrentes interessantes de outros fabricantes incluem o Lenovo ThinkPad X1 Carbon, HP EliteBook 840 G4 e Toshiba Portege X30-D, alguns dos quais são mais econômicos que o Latitude, mas todos os quais são acompanhados por seus próprios conjuntos de prós e contras.
Por que escolher o Latitude 7380 quando a Dell já produz um portátil ultraportátil de excelente qualidade com o seu XPS 13? Principalmente devido às sensibilidades de negócio que são implicadas pela marca Latitude. Além do seu estilo preto, elegante e discreto, o 7380 oferece um teclado superior, um touchpad com botões físicos separados, uma porta Ethernet, uma garantia mais longa e opções de manutenção muito mais flexíveis. Custa um pouco mais do que o XPS, mas é um pequeno preço a pagar se o trabalho for feito.
