Pro
Contra
Um ponto de venda importante da maioria dos portáteis de negócios é a capacidade de conectar facilmente estações docking ou baterias externas. Agora que a série Latitude 5280/5480/5580 deixou de lado o E-Port, o Thunderbolt 3 está se tornando ainda mais crucial para suportar recursos adicionais. Infelizmente o Latitude 5280 carece de ambos e, consequentemente, é menos versátil do que o 5480 e o 5580, embora seja menor e mais portátil. Além disso, a ventoinha do sistema está sempre ativa, o qual achamos desnecessário para um portátil que ostenta apenas processadores classe U.
Se as desvantagens acima não forem um obstáculo, no entanto, então o 5280 se destaca na maioria das outras categorias. Sua porta USB Type-C ainda será uma saída para DisplayPort de monitores externos e o novo chassi é muito mais leve que o E5270 sem ser notavelmente mais frágil. As durações da bateria já são excelentes na opção de bateria de gama média e preservar as saídas VGA e HDMI deve ser útil em lugares como universidades e da salas de conferência. O desempenho da CPU em particular é impressionante, pois o processador é capaz de manter velocidades máximas do Turbo Boost, mesmo durante cargas de trabalho muito altas.
Recomendamos que evite a muito pobre tela 768p e opte pela opção 1080p mais brilhante, com SSD primários mais rápidos. A melhoria na resolução e no brilho tornará o portátil mais confortável de usar e o investimento vale totalmente se o sistema for usado com frequência sem monitores externos.
Pode levar algum tempo se acostumar ao teclado um pouco esponjoso, e os usuários com mãos maiores podem querer evitar essa categoria de tamanho especial para digitação pesada. O 5280 é mais para usuários em constante movimento do que algo para estar em um lugar fixo em casa ou no escritório.
