Mais uma vez, uma máquina da série Dell Latitude 7000 nos deixa completamente impressionados. Juntamente com os ThinkPads da Lenovo e os EliteBooks da HP, os Latitudes sobressaem do resto da concorrência empresarial. Eles são cuidadosamente projetados, atualizados com inteligência e revisados com cuidado. Enquanto o 7490 é uma mera atualização iterativa do 7480 em todos os sentidos, realmente deixa pouco a desejar. A carcaça é robusta, discreta e atraente, o peso é aceitável, os dispositivos de entrada são excelentes, o desempenho é muito bom, a duração da bateria é longa e é um companheiro silencioso. As poucas áreas de melhoria que gostaríamos de ver são opções de tela para igualar seus concorrentes, melhor gerenciamento térmico e melhores alto-falantes.
Mais uma vez, uma máquina da série Dell Latitude 7000 nos deixa completamente impressionados. O Latitude 7490 de $1.709 hoje, é absolutamente digno de consideração por qualquer pessoa no mercado em busca de um portátil corporativo premium.
A configuração menos cara de hoje não tem o Core i7, o armazenamento NVMe, a tela sensível ao toque e alguns dos recursos biométricos e de segurança da unidade de teste de abril, mas também é de apenas $1.709 (comparado os $2.000 do modelo anterior). Aqueles que não precisam de memória dual-channel ou de qualquer das omissões listadas anteriormente, não encontram muito do que reclamar nesta configuração. Junto com o X1 Carbon, T480s, HP EliteBook 840 G1, e Latitude 7390, o Latitude 7490 merece consideração por qualquer pessoa no mercado à procura de um portátil corporativo premium.
