Contra
O Dell Chromebook 11 3181 é uma história de muito pouco, muito tarde. O dispositivo parece ter cerca de dois anos, apesar de seu lançamento relativamente recente. Isso é aumentado pelo desempenho sem brilho do dispositivo, baixa qualidade de construção e tela horrível. Não há razão para considerar o Chromebook 11 3181 quando o irmão 2-em-1 pode ser adquirido por apenas $50 a mais. O formato conversível do 2-em-1 é muito mais adequado para a integração de aplicativos Android, e a qualidade de construção do 2-em-1 é muito superior.
Apesar de ter sido lançado recentemente, o Chromebook Dell Inspiron 11 (Chromebook 11 3181) já parece velho. Considerando que o dispositivo é superado de várias maneiras pelo Acer C740, um Chromebook lançado há três anos, o Chromebook 11 3181 certamente não está se esforçando entre os dispositivos econômicos.
