Contra
O Dell Vostro 15 é um bom portátil de escritório Que haja alguns compromissos em comparação com portáteis empresariais mais caros não deveria ser uma surpresa. No entanto, não existem problemas sérios que nos fariam desistir de comprá-lo. É claro que a tela TN FHD é afetada pelos altos desvios das cores e uma forte tonalidade azul de fábrica, mas certamente isto não nos faria desistir para as típicas tarefas de escritório (correios, folhas eletrônicas, apresentações, vídeo conferências, etc.). Nos também testamos os paineis TN com ângulos de visão piores.
Existem outras desvantagens como os medíocres dispositivos de entrada, as taxas de transferência bastante lentas do WLAN, os recursos de segurança e os alto falantes pobres. Alguns destes aspectos podem ser melhorados com atualizações opcionais (iluminação do teclado, sensor de digitais, outro módulo WLAN).
O Dell Vostro 15 é um portátil de escritório caro com bom desempenho e uma bela carcaça. Uma tela IPS opcional seria uma bela adição.
Gostamos do bom desempenho, a operação silenciosa e o belo chassi, que não revela o preço de nível de entrada baixo. O Vostro 15 não tem que se esconder atrás de sistemas mais caros, em termos de estabilidade. Primeiramente gostaríamos de ver uma teclado melhor, bem como uma tela IPS, pelo menos como uma opção.
Tanto o HP ProBook 450 G4 como o Acer Travelmate P259 sofrem com telas fracas. Estamos analisando o recém-chegado Lenovo ThinkPad E570, que poderia ser um concorrente muito forte, baseado nos resultados dos nossos testes iniciais (FHD-IPS).
