Contra
Os usuários de escritório notarão duas desvantagens no bem-projetado Lenovo Yoga 720-12IKB - o módulo WLAN comparativamente lento e, mais importante, os tempos de duração que não podem cobrir um dia útil completo. A escolha da tela é muito boa, exceto para edições sérias de imagens, e os resultados do benchmark do SSD lento não afetam o bom desempenho do sistema. A variedade limitada de portas é comum entre os conversíveis compactos, portanto, dificilmente podemos criticar o Yoga aqui.
A estabilidade da carcaça não é perfeita, mas ainda é um chassi bem-sucedido com um bom design e boa qualidade de construção. O Active Pen, os dispositivos de entrada decentes, incluindo a tela sensível ao toque, bem como a operação eficiente, fria e muito silenciosa, são outras vantagens.
O conversível Lenovo Yoga 720 12 versátil e compacto é acessível e atende quase todos os requisitos para usuários empresariais em constante movimento. A única desvantagem real é a limitada energia da bateria.
Em suma, podemos recomendar o modelo de teste.
