Contra
A diferença entre o LG Gram14T990 mais antigo e o LG Gram 14T90N mais recente é marginal, na melhor das hipóteses. A atualização do processador é quase imperceptível, o que deixa o Thunderbolt 3 como o principal fator de distinção entre os dois modelos. Se você planeja utilizar dispositivos baseados no Thunderbolt 3, como estações docking e monitores externos, encontrará valor no Gram 14T90N. Caso contrário, economize algumas centenas de dólares e opte pelo Gram14T990.
Existem algumas vantagens notáveis que o conversível da LG tem sobre os concorrentes. O baixo peso torna mais fácil o uso no modo tablet do que o ZenBook 14 Flip e as duas baias de armazenamento interno são uma raridade, considerando a categoria. Mesmo assim, o sistema se sente com pouca energia para o preço, especialmente em termos de potencial gráfico, enquanto recursos de privacidade comuns, como um obturador de webcam ou câmera IR, não estão presentes. Talvez uma CPU Core i7 Ice Lake funcionasse melhor considerando o público-alvo. A tela também poderia ter sido mais brilhante para maior visibilidade ao ar livre.
O Gram 14T90N é um conversível de US$ 1400 com uma CPU de baixo desempenho e nada mais. Você precisará usar seu peso leve, bateria de longa duração e a porta Thunderbolt 3 para aproveitar ao máximo o sistema.
