Contra
A Dell redesenhou seu Latitude de 13,3 polegadas sem mudar muito. Pelo menos no mais escuro dos dois modelos, com sua carcaça de fibra de carbono que tivemos em análise. O SKU de alumínio parece muito diferente do seu antecessor.
A carcaça compacta de alta qualidade é um dos destaques do Latitude, assim como o teclado confortável. A tela está equipada com uma camada de toque que permite entradas adicionais. O leitor de cartões microSD é facilmente acessível e incrivelmente rápido. Além disso, o Latitude possui várias portas e recursos de segurança. Também é facilmente atualizável graças a dois slots de RAM, um slot WWAN livre e um modem Wi-Fi com soquete. Ele vem com 3 anos de garantia no local/em casa e funcionou por quase 11 horas com bateria em nosso teste de Wi-Fi.
Uma de suas principais ressalvas é o touchpad. Se sente barato e não gostamos ou desfrutamos de sua superfície plástica áspera. Dado que o Latitude não possui um TrackPoint, os usuários serão forçados a recorrer a mouses externos. Também não gostamos muito da porta de carregamento proprietária e teríamos preferido uma segunda porta USB-C ou Thunderbolt 3 com fornecimento de energia. A Ethernet está ausente, e a tela supostamente mate acabou sendo sendo semi refletiva. Esperávamos que a Dell fosse mais precisa em suas especificações em relação a esses detalhes.
O desempenho da CPU foi bastante ruim e pior do que no próprio antecessor do Latitude 7300. Aqueles com a CPU i7 não estão obtendo o desempenho esperado. Um problema inaceitável para um portátil desse preço.
O ruído agudo do ventilador foi outra desvantagem, embora o ventilador não tenha sido particularmente alto em geral. E por último, mas não menos importante, teria sido bom ter uma opção de tela mais brilhante disponível.
Um desempenho geral sólido com um ponto crucial: A CPU Whiskey Lake acabou sendo mais lenta que o processador do antecessor.
Se você deve considerar isso como um obstáculo para a compra, depende de você. No lado positivo, o portátil empresarial Dell Latitude 7300 oferece uma excelente duração da bateria e excelente capacidade de atualização.
