Os dispositivos de entrada acima da média foram impressionantes. O teclado é caracterizado por um deslocamento regular e bom. Confirmamos o mesmo no substituto do mouse, o qual poder ser chamado assim com todo direito. Gestos simples e multi-touch são implementados perfeita e imediatamente. Embora o modelo de teste possa ser colocado na categoria empresarial de gama média, a tela IPS instalada atinge boas taxas em contraste e brilho.
Em termos de desempenho, o portátil da Dell enfrentou seus rivais e demonstrou ser um poderoso oponente. O Latitude também foi sólido nas taxas de emissão. Como o Lenovo ThinkPad T440s, a curva de temperatura deve ser melhor.
Infelizmente, a duração da bateria não é suficiente para todo um dia de trabalho. Embora a Dell não ofereça uma bateria maior, há uma solução externa que não é muito barata, a quase 160 Euros (~$198). O portátil Latitude E5450 é recomendável para a rotina empresarial. No entanto, também seria aconselhável olhar outros portáteis similares.
